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 effificient 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.
    • Improved version of the Hip-Hop cortical parameterization process
    • The MarsAtlas cortical parcellation model has arrived !
    • Sulcal pits computation for individual subjects.See in Anatomy section.
    • 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

See the BrainVISA Changelog for more details.

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.

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

Morphologist provides a reorganized pipeline, and improvements in meshes.

See the changelog for more details.

September 6th, 2012, New BrainVISA release: version 4.3.0

In this version, it is possible to store history information about output data generated by Brainvisa processes. History management can be activated for a database through its expert settings activate_history option. History of data can be consulted via the Database browser.

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

See the changelog for more details.

Amongst noticeable changes, the Cortical surface toolbox (LSIS/CNRS, Marseille) has also been significantly improved.

New: (2013/11/18) Vobi One, a new toolbox for functional optical imaging, has just been released by the INT/CRNS in Marseille. See the toolboxes page, or the dedicated web site.

February 16th, BrainVISA bugfix update: version 4.2.1

This version brings a few bug fixes, and minor improvements.

See the changelog for more details.

February 3rd, 2012, New BrainVISA release: version 4.2.0

In this version, it is very easy to do parallel computing in BrainVISA. Indeed, Soma-workflow has now been completely integrated in BrainVisa: processes (pipelines) may be run through a "Run in parallel" button, which allows to dispatch processing across local processors, or on a remote computing resource. A specific GUI allows to control and monitor all executions. Change the user level to Advanced or more in BrainVISA preferences to use this new feature. More information in the BrainVISA manual.

See the changelog for more details.

January 19th, 2012, New release of Soma-workflow: version 2.1

See its main page for details about this new version.

September 14th, 2011, BrainVISA bugfix update: version 4.1.1

This version brings a number of bug fixes, and of minor improvements.

See the changelog for more details.

August 24th, 2011, New release of Soma-workflow: version 2.0

This tool helps submitting parallel computing to various computing resources. See its main page for more details.

July 5th, 2011, New sulci atlas available

A set of 125 sulci labels for both hemispheres was already used in BrainVISA Morphologist toolbox for sulci identification with SPAM method (since BrainVISA v. 3.2.1 ). Now this work is also available as a standard anatomical atlas of cortical folds shaped as a volume of labels in the MNI space.

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 of improvements, notably a new version of the T1 pipeline named Morphologist which is more robust and efficient.

See the changelog for more details.

November 22nd, 2010, BrainVISA bugfix update: version 4.0.2

This version brings a number of bug fixes, and of minor improvements.

See the changelog for more details.

August 2nd, 2010, BrainVISA bugfix update: version 4.0.1

This version brings a number of bug fixes, and of minor improvements.

See the changelog for more details.

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'll may have to port them to Qt4 (See Porting to Qt 4 on Qt documentation pages). This version's sources are still compatible with Qt3, so if you compile from the sources, you can still use Qt3. Note that the compatibility will not be guarantueed anymore in BrainVISA 4.1.

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

See the changelog for more details.

January 27, 2010, bugfix update: version 3.2.1

This version brings, as usual, a number of bug fixes, and of minor improvements. A few noticeable changes also, including some improvements in the T1 and Sulci toolboxes, a new simplified Anatomist-based viewer, etc.

See the changelog for more details.

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. See the changelog for more details.
