Febuary 2016, new BrainVISA release: version 4.5.0

  • Morphologist:
    • Imporoved meshes.
    • Additional optional step to skull-strip the brain and use it in a second normalization step, to improve alignment robustness.
    • A variant of the pipeline is the premise to the future redesigned pipelining system (Capsul): “Morphologist CAPSUL iteration”. It should behave the same way, but preparing a large iteration on many subjects should be more efficient and faster. The process produces a workflow, to be run in soma_workflow_gui
  • Morphologist UI: a new simplified interface to the Morphologist pipeline. See the documentation
  • Cortical_surface:
    • New sulcus parameterization, faster, more robust, better properties.

    • The Depth Potential Function (DPF) computation is now included in the Anatomy / tools section
  • Anatomist:
    • Supports Wavefront .obj format
    • Supports NIFTI-2 format
    • Supports Trackvis .trk format
    • Can save and reload textured meshes with colormap (as .obj), especially convenient to import/export with other software like Blender.
    • Shader-based rendering of fibers, with coloring
    • Major improvements in SurfPaint module
    • Improvements in transparent objects rendering (possibility to sort polygons)
Anatomist/BrainVISA changelog

November 18th, 2013, New BrainVISA release: version 4.4.0

This version allows a more incremental management of databases, allowing incremental updates after distributed computing. A new database organization (fully compatible with the previous one) is also provided. Many graphical and practical improvements have also been added, in addition to "traditional" bug fixes. See the Axon detailed changelog.

Anatomist has also undergone some important improvements, in graphical interactions, as well as some new objects types. See Anatomisr detailed changelog

Morphologist provides a reorganized pipeline, and improvements in meshes.

    May 17th, 2011, New BrainVISA release: version 4.1.0

    In this version, an important change for the developers should be noted : the build tool used to compile from the source code has changed. We dropped our home-made tool build-config and replaced it with the standard tool CMake, a cross-platform, open-source build system.

    This new package compiled with CMake doesn't need an installation step anymore. You just have to download it and uncompress the archive, then it is ready to use. Thus, there is no setup script or program anymore. The cartopack.sh script that used to add the package paths in environment variables have been renamed into bv_env.sh.

    The package includes a new tool that helps submitting parallel computing to various computing resources: soma-workflow. The documentation is here.

    This version also brings a number of bug fixes, and improvements:

    • BrainVISA
      • Text search available in the log throught ctrl+F and F3 keys
      • Text viewer available for more data types (csv, xml files).
      • [programmers] Brainvisa now uses sip QString API version 2, so it not possible to use QString and QStringList classes anymore, python types should be used instead.
      • Fix graphviz packaging which make generation of ontology documentation with types inheritance graphs available.
      • Update in programming documentation about GUI customization
      • T1 MRI toolbox
        • New T1 pipeline named Morphologist. This new version is more robust and efficient.
        • T1 Normalization processes (using FSL or SPM) have been moved from fMRI to T1MRI toolbox. So, it is now possible to choose normalization instead of manual localization of AC/PC in the anatomical pipeline without having the fMRI toolbox installed.
      • Sulci toolbox
        • New process SPAM models installation to install SPAM models for sulci recognition. The installation of the required models is checked in the Morphologist pipeline.
        • Add new 2011 ANN models to sulci recognition available models. These models implement the older method, on the same (newer) learning database as the one used for SPAM models.
        • Bug fix in iterative mode of a sulci graph viewer
      • BrainRAT toolbox
        • Add RGB/RGBA background estimation to subsampling and to intra volume registration process
        • Add advanced slice replacement process
    • Anatomist
      • New surfacic ROI drawing toolbox: it is now possible to paint on a mesh (into a texture), and use curve drawing tools which include curvature constraints. This toolbox is developed in Marseille by O. Coulon's team, mainly by A. Le Troter.
      • Update and additions to pyanatomist documentation.
      • Bug fix in FusionRGBAVolumeMethod fusion method
      • Bug fix in palette update in a MultiTexture fusion

        • Helper functions to create the main Aims data types
        • Allow additional constructors arguments for volumes and textures (build from another volume, or a numpy array...)
        • Big fix in TimeSurface erase function

    November 22nd, 2010 bugfix update: version 4.0.2

    This version brings a number of bug fixes, and improvements:

    • BrainVISA
      • New progress bar in processes and pipeline windows.
      • Viewers and Editors are now available for list of data. The default viewer is an iteration of the viewer for the type of data in the list.
      • Fix background and foreground color of choice nodes in pipeline graphical interface.
      • Fix iteration on Series of 3D volume (Import fMRI data)
      • Database browser: enable visualization of unrecognized data if a viewer that accepts the data format exists.
      • Fix commands log in windows version.
      • Documentation panel : enable links with anchor and open web links in a real web browser when possible.
      • Browse button in process iteration dialog always opens the dialog that enables selecting several files at different location on the filesystem. This action was only available through right click before.
      • Improvement of database update when a process finishes : intermediate directory items created by the process are inserted in the database; output parameters of a sub-process not in a pipeline are inserted in the database.
      • Improvement in Morphometry statistics process : output parameters are now output_directory and output_filename_prefix instead of output_prefix and have default values.
      • Improvement in DicomToNiftiConverter process : enable choosing the output filename and giving a directory containing dicom images instead of a file as input parameter.
      • New importation process to import a T1 MRI from a Dicom directory using Mricron Dicom converter.
      • Fix Single file to serie process : generate the numbers of the serie with a fix number of digit to ensure that the files of the serie are in the correct order.
      • T1 MRI : new sulci voronoi step before the folds thickness step, to allow saving and reusing the sulci voronoi maps; New type for lesion mask used in the brain segmentation parameters.
      • Sulci : new processes to calculate the mean distance from a lesion mask to sulci.
    • Anatomist
      • New option in Anatomist config and preferences panel: clipBrowserValues. This option allows to limit the size of strings displayed in browsers attributes, and avoid crashes due (probably) to too large pixmaps in X servers in some specific cases.
      • Gradient palette available for RGB images.
      • Improvement of tooltips on graphs in "display property" mode
      • Fix rendering problems using ATI cards and drivers on S16 volumes.
      • Fix ROI cursor display

    July 22th, 2010, New version of BrainVISA fMRI toolbox : 4.0

    The 4.0 release of the fmri toolbox comprises the following new features:

    • Improved and more robust cortical surface-based analysis procedures.
    • Improvements in multi-subjects analysis, such as the introduction of second-level design matrices.
    • Better integration of General Linear Model in the volume and on the surface with high-level operations (group analysis, reproducibilitry assessement, parcellation and functional landmark characterization).

    It is compatible with BrainVISA 4.0.

    June 15th, 2010, New version 4.0

    This is the first version of BrainVISA using Qt4 API. Be careful, Qt4 API is quite different from Qt3. If some of your own processes use Qt, you may have to port them to Qt4 (See Porting to Qt 4 on Qt documentation pages). This version's source code is still compatible with Qt3, so if you compile from source, you can still use Qt3. Note that the compatibility will not be guaranteed anymore in BrainVISA 4.1.

    This new version also brings a lot of bug fixes and some improvements in user interface:

    • BrainVISA
      • New contextual menu on pipelines and iterations enabling easy selection, deselection, opening and documentation display of the different steps.
      • Visual feedback in processes graphical interface to show which parameters have been modified.
      • BrainVISA documentation panel: keyboard shortcuts for contextual menu items and a new button to reload the current documentation page.
      • Attributes sorting enabled in database search interface (available only in Qt4 version).
      • Import T1 MRI: the default value for subject attribute is the name of the file.
      • Types and formats documentation now shows the hierarchy rules for all available ontologies
      • Fix: parameter exactType in WriteDiskItem initialization is now taken into account.
      • Sulci toolbox - ergonomy improvements in Sulci recognition pipeline: combo boxes to select the recognition method.
    • Anatomist
      • OpenGL-based selection infrastructure. Selection functions for meshes and polygons have been included in Anatomist. In "debugger" mode (userLevel >= 3) this mode replaces the older graph/bucket selection mechanism. When correctly tested, it will fully replace it.
        A little texture drawing code example is now part of the examples.
        The new infrastructure is not optimized at all yet, so, drawing is slow, but we will improve it in time to avoid unnecessary OpenGL renderings.
      • Python bindings and the python API have been slightly improved.
      • New command: ApplyBuiltinReferential
      • The file browser for loading objects now shows all file extensions used by supported objects files. Extensions list is built dynamically from the loaded readers.
      • Clearer tooltips in the referentials window.
      • Many problems have been fixed when Anatomist is built using Qt4. Some modules had not been ported or tested, and Mac and Windows ports had not been tried. Now things are mostly tested.
    • AIMS
      • Improvements and fixes in various IO modules: Dicom, Nifti, Gifti, FDF
      • Beginning of a SQL database format for graphs (QSlite files for now). This will allow partial reading and queries in large graphs databases. But the module is still experimental and the SQL database schema will probably change, so it should not be used yet to store important graphs. Conversion from and to the .arg format are still possible.

    January 27, 2010, bugfix update: version 3.2.1

    This version brings, as usual, a number of bug fixes, and minor improvements. A few noticeable changes also:

    • Binary packages
      • Something we just forgot to mention but was already present in version 3.2: Linux packages include a software OpenGL library (Mesa) which may be used in place of the system one in case of 3D drivers rendering problems. To enable it, just move the files in <cartopack_directory>/lib/mesa/ into <cartopack_directory>/lib/ and re-run Anatomist/BrainVisa. It is slow because it does not make use of the 3D hardware at all, but should work and display correctly in all cases. Only use it if the system OpenGL does not work well.
      • A few system libraries have been added to the binary distribution to overcome compatibility problems on some systems.
      • The fMRI toolbox will also be released for the Linux Mandriva 2008 x86_64 (64 bits) version.
    • BrainVISA
      • A serious bug has been fixed on the database system on Windows, it fully made the database unusable in 3.2 version (on Windows). It is now fixed.
      • T1 pipeline: the pipeline can now make use of the spatial normalization processes of the fMRI toolbox to replace the manual AC/PC clicking step. To make it available, you need to have the fMRI toolbox installed, and also have either FSL or SPM5 (+ Matlab) installed and present in the PATH. As the fMRI toolbox is only released for Linux, you will not be able to have it on Mac and Windows (unless you install the sources of the toolbox, actually at least the FSL normalization does work on Mac).
      • Sulci recognition: The various and more advanced sulci recognition methods of Matthieu Perrot's PhD work have now been released. They need to install additional models archives. See the docs of the SPAM-based recognition processes.
      • A few little improvements to make database and T1 import processes more practical.
    • Anatomist
      • A new simplified viewer application has been developed: anasimpleviewer.py. It offers a simple and easy interface in a single window using a fixed 4-views layout, which is more classical and more convenient for inexperienced users. It is a restricted and constrained use of Anatomist capabilities. It has been developed in a few nights, at first to show that developing simple custom applications using Anatomist libraries is not so difficult and may be done quite fast in Python language...
      • A new plugin allows to tune the palette (contrasts) of objects using the mouse right button (+ shift/control keys) directly on 2D/3D views without opening the palette window.
      • A better histogram window plugin, based on Matplotlib, which offers interactivity (zooming, saving/snapshot in either bitmap or vector formats, ...)
      • The ROI drawing cursor hs been fixed and re-activated on Mac

    November 05, 2009, New BrainVISA release: version 3.2.0

    This new release is mainly due to internal changes and reorganization of our sources repository. This sources repository and web interface for bug tracking are now accessible for open-source parts to contributors. See this page for details.

    This release also brings many bug fixes and improvements :

    • Binary Packages
      • The windows version should work on Windows Vista.
      • A 64 bits binary package is now available for Linux.
      • The Mac version is now built on an Intel machine. It is no longer compatible with PPC processors, but it should run way faster on Intel Macs.
    • BrainVISA
      • Several improvements on BrainVISA databases :
        • Optimization of databases requests. The results are now shown as a table of attributes values.
        • Easier database request with existing values of databases attributes selectable
        • Databases can be moved without needing update.
      • DiskItem selection window cannot become higher than screen anymore
      • No more useless *.minf created by processes
      • Iteration control : it is possible to stop the current iteration or all iterations.
    • Anatomist
      • VTK plugin by Pierre Fillard, which allows to render VTK objects, and especially enables a mix between Anatomist and MedInria objects.
      • GIFTI format IO support for meshes and textures

    This update brings more bug corrections and optimization.

    This package is distributed with the new BrainRAT toolbox dedicated to ex-vivo 3D reconstruction and analysis.

    Starting with BrainVISA 3.1.4, the fMRI toolbox will be distributed separately as a downloadable add-on package to provide it its own visibility.

    October 3, 2008, bugfix update: version 3.1.3

    This update brings more bug corrections and optimization of database access. This package is distributed with a more recent sqlite library.

    September 3, 2008, bugfix update: version 3.1.2

    This update brings more bug corrections, including some database importation problems fixes.

    In Anatomist, a noticeable improvement is the presence of a new gradient palette edition module which may be quite useful.

    August 7, 2008, bugfix update: version 3.1.1

    A number of bugs have been fixed since brainvisa/anatomist 3.1 have been released, so a new package is now available.

    June 9, 2008, new release: version 3.1

    Finally, a new release, after about 3 years of life of version 3.0.x.

    It should work on Linux (Fedora 4 or equivalent and newer distribs), MacOS 10.4 or newer, and Windows XP.

    Amongst the most noticeable changes, we can cite

  • A fMRI module for BrainVISA, partly using Matlab and SPM, on the Linux version only at the moment
  • A new and faster database system in BrainVisa, which will need a conversion of older databases
  • the AimsAlgo part becomes open source (GPL/CeCILL license)
  • A volume rendering module in Anatomist
  • ...
  • May 05, 2006, package update: 3.0.2

    A bugfix update that fixes several problems, especially stability issues on Windows.

    The Mac version now runs on MacOS 10.4 (and not on 10.3 anymore).

    Solaris and Irix versions are still not maintained.

    October 17, 2005, package update: 3.0.1

    A bugfix update that fixes an important bug in the diffusion/tracking algorithms, a number of instabilities (rare crashes) in Anatomist, and adds some "minor" improvements, like multiple matlab versions support in BrainVisa, some optimizations in Anatomist when many complex objects (graphs) are loaded...

    Solaris and Irix versions are still not maintained (the solaris problem might have been solved recently but we need more testing and repackaging).

    June 29, 2005, brand new release: version 3.0 is out

    Finally we managed to release the new version of all of our software. Every project within the package has now version 3.0 (for simplicity).

    This package is released on Linux, Mac OS X and Windows XP systems, and not for Solaris or Irix. This limitation is due to technical problems on our side that may or may not be solved one day. Sorry for this.

    See the release notes and docs for an overview of new features and changes.

    Dec. 2, 2004, stable release update: 2.3.5

    Just after the last update release, we found some bugs in Anatomist display (volume fusions in sagittal slices), and in the Mac version of BrainVisa (and probably the Windows version too), so here is another fix for these problems.

    Nov. 19, 2004, stable release update: 2.3.4

    A bugfix update package (2.3.4) is available in the download section. It fixes some bugs (especially on the Windows version), and includes minor improvements such as matlab support on Windows, SPM2 normalization matrixes importation, and a better installation script. The package should work now when installed in a directory containing space characters.

    Sep. 28, 2004, MacOS X fix update: 2.3.3

    Well, the Mac version has not been maintained very regularly, and I have just noticed that the 2.3.2 binary version has been all messed-up, the distribution is incomplete and out of order. I am sorry about that (but nobody has complained!), the fact is that I didn't have a Mac machine to work on regularly. I have one now (thanks to Jean R�gis, La Timone).

    There is now a new binary package just for Mac, which runs on MacOS 10.3 and without the need of a X11 server, and compiled with optimization on. Be careful, there are still a few problems however:

  • Brainvisa run from the graphical interface of the Mac seems to frequently (and randomly) hang when running commands, so for this version at least, avoid running it by clicking on an icon, but use a terminal... We will investigate this strange phenonemnon when we have a bit of time...
  • This package may not work on MacOS 10.2 and earlier. I have not tried myself, but...
  • Jul. 8, 2004, stable release update: 2.3.2

    Finally we have released a new package (2.3.2) which fixes various bugs encountered in the 2.3 release. Amongst other fixes, we can cite:
  • fix in BrainVisa database hierarchy description which could cause an ambiguity in the anatomical pipeline
  • Fixes in filenames handling when filenames contain space charachers (which often happens on Windows)
  • etc. See individual changelogs accessible via the help pages for more details
  • We do not plan a new version before the end of 2004 because many changes have been started in both BrainVisa and Anatomist and we need time to finish, stablilize and test all the new features.

    Jan. 14, 2004, web server hosting change

    Our website has moved to another place. It is still accessible on its "official" name http://brainvisa.info, but as it used to be just a redirection, your browser has probably bookmarked it as http://brainvisa.free.fr. So please update your bookmarks, the old page will be removed in a short time.
    The new server should be much faster and more reliable, and will allow us to set up a bug tracking tool and a forum and other tools in the future.

    Jan. 6, 2004, MacOS X fix update: 2.3.1

    This is only a MacOS X-specific installation fix: it should overcome the "little squares" syndrom on Anatomist and BrainVisa which do not properly display text on some systems. Basically, I just upgraded some libraries (especially Qt) from the Fink project.
    Jan. 14: Well, no in fact, it doesn't seem to help on MacOS 10.3 - use the trick in the FAQ to get non-antialiased fonts in Qt.

    Dec. 18, 2003, new stable release: 2.3.0

    Featuring BrainVISA 1.6, Anatomist 1.30, Aims 2.13, Vip 2.5 etc.
    At last we are ready to distribute a new version of BrainVISA, Anatomist and all the other tools. Amongst other improvements, we can cite:
  • in BrainVISA:
    • easier database setup which can now be done via the menus
    • some improvements in the user interaction and viewers
    • mproved (althrough still not complete) help system
    • working diffusion / fiber tracking pipeline
  • In Anatomist:
    • minor GUI improvements: viewing images in radio or neuro convention, new setup options, visibility or usability comfort improvements
    • new functionalities in the ROI drawing module (morphological math operations...)
    • fixes and improvements in several volume formats IO...
  • Many other things which we did not keep track of. A bit more details are available in the different projects changelogs, accessible via the new documentation and help pages
  • And maybe most of all, this is the first stable release to include a Windows version.
    The Windows version is working and nearly fully functional, but there are still some problems in BrainVISA cleanup when exiting, and VIDA and ECAT volume formats are not supported. The other features seem to work well and processings produce the same results as the Unix versions.
    The cache problem of the test releases for Windows is fixed, but at the cost of being slower (possibly MUCH slower for large databases) because BrainVisa must systematically scan every directory when accessing the database.
  • Nov. 16, 2003, one more test package for Windows

  • this pack doesn't use any unix command anymore
  • communication failures between BrainVisa and Anatomist have been fixed (I hope!), after a long and hard fight
  • fixes little things like installation in path containing space characters, ambiguous files naming on case-insensitive filesystems, ...
  • C and C++ sources have been compiled with optimization flags so it may be faster
  • This is still definitely not the final version: there are still problems going on.
  • I have experienced cache update problems with BrainVisa (the cache doesn't update automatically, I have to make a "clearCache" and "updateCache" to make new files visible in the database). We have understood what is going on: Fat32 filesystems don't update directories modification date/time when a new file or directory is created inside it. There should be no problem on NTFS filesystems and on Unix Samba-mounted network drives. We will try to find a workarouond because it is very ennoying, especially when importing a new subject MRI.
  • BrainVisa still doesn't exit cleanly and some temporary files may not be deleted after it exits
  • Oh, by the way, this package has been built on a linux filesystem, so sources (python sources, C++ headers) are in unix ASCII convention. In the counterpart, files which were symbolic links are OK on this version.

    Nov. 04, 2003, another test package for Windows

    This package fixes some problem with the previous one:
  • some missing DLLs and paths in python prevented brainvisa from correctly running commandlines (so almost nothing didn't work!)
  • a bunch of unix-only commands (like rm, cp, mv, touch...) have been removed, but some are still around...
  • a better guess of the home directory is done so that .brainvisa and .anatomist directories may be in a sane place even on other windows than XP
  • Nov. 02, 2003, first development package for Windows

    There are still some problems (Brainvisa exits uncleanly and leaves some temporary files, communications with Anatomist is sometimes lost...) but the main features are working: BrainVisa, Anatomist and the image processing tools are there.
    Some volume IO formats are not supported at the moment: vida and ecat formats are not compiled in the package. These formats require some libraries I don't have on Windows (rpc library).
    But this is one of the last main steps towards the universal portability of the platform...
    This test release is meant essentially for ourselves for debugging purposes, not for end users yet. A new version is planned soon for all platforms (this month if we can take the time to do it).
    Technically, I used the gcc compiler from the MinGW environment, and our configuration tools (build-config/configure/maker) in an unix-like environment (Msys bash shell coming with MinGW).
    Compiling with the gcc compiler from the Cygwin distribution is also possible (and certainly easier in fact), and would allow to build vida and ecat format support because cygwin includes the missing rpc library. But for licensing reasons, we cannot use cygwin: codes compiled with cygwin link against the cygwin DLL which is GPL'd and must be used only for GPL'd code (which is not the case of our algorithms).
    Building with Microsoft C++ compilers (Visual Studio .net) was not possible, the compiler fails on some heavily templated C++ code: don't try the adventure, it's useless.
    The binary distribution contains a copy of the commercial version of Qt library DLL, and of the commercial version of PyQt for Windows.

    May 23, 2003, stable version update: 2.2.3

    Various little fixes (which may be important in some specific cases) in the programs and the package installers, amongst which:
  • Anatomist: fixes in buckets 3D renderings
  • Brainvisa: some problems with parameters links have been fixed
  • MacOS X installer: we used a tar program which was incompatible with Apple's tar, it's fixed now
  • Linux/RedHat9 installer: we switch to the older threading system because the new one causes problems with Python threads
  • Fixes in some lower-level commands: AimsClusterArg, ...
  • Apr. 29, 2003, stable version update: 2.2.2

    A few little fixes (mainly for linux):
  • Anatomist: fixed a crash that could occur while in ROI edition and playing with several volumes with palette windows open
  • Anatomist: fixed the color change of some widgets which does not work with some KDE3 styles (this fix disapeared by mistake in the last stable anatomist release)
  • Anatomist: menu options to save the texture of some textured objects
  • We include again libcrypto and libssl in the linux package since they are required for some python modules
  • Apr. 15, 2003, stable version update: 2.2.1

    This new distribution fixes some installation problems (and offers more precise installation instructions), and fixes a few BrainVisa bugs (the help processes, diffusion package...).

    Apr. 07, 2003, new stable release: 2.2

    A new version of all software has been released, version 2.2 of the pack. Binary packages for Linux (RedHat 7.3 and compatible distribs), Solaris, Irix and MacOS X have been uploaded to the ftp site. See the downloads. We changed the installation procedure: see the .README file with each package. There is now only one file to get, the installer is in it, but you have to unpack it yourself before running the install script.
    It features Anatomist 1.29, Brainvisa 1.5, Aims 2.12, Vip 2.4...
    Main changes: bugfixes (mainly in SPM format IO), many changes in BrainVISA, shfj library is now renamed cartobase

    Feb. 28, 2003, another MacOS X update

    Other little fixes. You may still need to setup the default Qt font using qtconfig. See the FAQ for details

    Feb. 25, 2003: first MacOS X release (development)

    A first development version for Mac/darwin compiled for X11 server. I hope everything is in the package... It has not been thoroughtly tested yet...

    Nov. 08, 2002: new stable release 2.1

    This release is a version upgrade for ALL software: BrainVISA 1.4, Anatomist 1.28, etc.
    Amongst the most important changes:
  • Introduction of functional preprocessing using SPM and Matlab in BrainVISA. This will evolve and more support for higher-level functional processing will be added in futire releases. You must have Matlab and SPM installed to use them.
  • If you wish to build from sources, the gcc-3.x compilers can now be used to build all our C++ code.
  • Binary package notes:
  • This release is the first stable release to provide a binary package for Irix
  • On Linux, we reverted from the behaviour of 2.02-2.04 distribs and we systematically install Qt library again, because there may be system libraries incompatibilities (C++ library), for example on RedHat 8 or Mandrake 9 systems using gcc-3.2. So DON'T USE THE SHFJEnvironmentVariables.sh/.csh scripts in your .cshrc/.bash_profile config scripts ! (or check they are compatible with your system first) - see the FAQ for more details.
  • Sep. 24, 2002: new stable 2.04 release for linux and SuSE-specific development release

    (Installation fix release)
  • 2.04 stable release fixes an installation problem again: home-compiled Qt with good Jpeg support
  • SuSE-8.0 main (devel) release has been made because of system libraries incompatibilities with RedHat

  • Changes between 2.04 and 2.03: Ooops, our Qt lib didn't support jpeg (!)
    Changes between 2.03 and 2.02: installation fix: provide a home-compiled Qt library instead of RedHat's customized one, and install it only if the target system doesn't already have it

    Aug. 22, 2002: first complete binary package for Irix

    An Irix package is now available (development version) and contains the full set of programs and libraries: brainvisa, anatomist and all tools

    09/08/2002: new stable release 2.02

    Featuring Anatomist 1.27, BrainVISA 1.3 etc.
    Changes between 2.02 and 2.01: installation bug fixes
    Changes between 2.01 and 2.0: fixed a few broken functionalities in Anatomist 1.27 and some low-level Aims commands
