I think PyXML-0.8.3.win32-py2.3.exe is to be used with Python 2.3 (the one provided with BrainVISA).

Link between BrainVISA and SPM2 is done with XML files. To get access to these processes (still under developpement), PyXML must be installed. It should be included in our binary package. We are checking this out. To detect R software, BrainVISA scan the directories of the PATH environement variable...

Numeric is an obsolete package that is beign replaced by Numarray (see http://www.pfdubois.com/numpy). I did not installed Numarray to avoid compatibility problems with existing processes. I will have either to switch form Numeric to Numarray or to install both (the web site says it is possible).

Could you give a bit more information about what you tried and how it failed ? T o process diffusion data with BrainVISA you should follow the following steps : 1) Create a database. This is a directory with a specific structure. By choosing Preferences->Databases menu, you can 'Add' a new database....

We do not have written a description of the bucket (*.bck) format yet. I will try to write one as soon as possible and put it one the web site. The only other solution I can propose to access to tensor values is to build one 3D image for each coefficient. This can be done with the AimsDiffusionScala...

There was serveral typo bugs in BrainVISA. In your version, a DiskItem.fisrtFullPathsOfEachSerie is defined. In the conversion process an 's' was added. I corrected the developpement version by using fisrtFullPathsOfEachSeries everywhere. If you cannot wait for a new package, the easiest temporary s...

Hi Olivier,

If you want to build the optional aimstiff module (allowing aims to read images in tiff format), you need to install libtiff and the corresponding headers. Classical Linux distributions provide a package called libtiff-devel that you should install.

Hi Denis,

I think the problem is not in your code but in BrainVISA. I will investigate and correct it as soon as possible.

Hi Mélanie, This converter has been developped to handle SPM images (which are series of 3D images) in BrainVISA database system. It uses a rather complicated system that can group several SPM files in a single DiskItem. To date, this grouping can only be done through th hierarchy system. It is not ...

We do not have the Excite system on our GEMS Scanner yet. We are going to get some data from this system this week to see if the way data are stored have changed beween the old and the new GEMS system. We will post a message on this forum when we have more information.
