Hi, You can investigate by using and computing transformation matrix (.trm file - to start you will find some information on the forum by searching "trm" keyword), the Aims command lines (AimsManualRegsitration, AimsMIRegister) or some BrainVISA processes like "Registration -> Registr...

Ok
I know your email. I'm going to send you the training book.

Hi,

I have written an english training documentation. There are basic and advanced levels. Do you want to try it to start with Anatomist and could you give me your opinion before we will propose on the web site ?

Isa

Could you try with other data ?
You can download demonstration data on the web site http://brainvisa.info/downloadpage.html ortherwise I can send you data.

Isa

I hope and suppose Denis will have a better idea.
Which kind of data did you try to display ? T1, T2, 2D image .... ?

Hi, Your chipset seems compatible with OpenGL. We already worked on this kind of worksation with graphic chipset and it was ok. Did you try to change the graphical properties ? We often see a problem about the graphic acceleration and texture display. You can read a solution on : http://brainvisa.in...

Hi, What is the kind of sequence ? SPGR or IR ? Perhaps there is a confusion about this parameter. Normaly, the algo can detect this parameter but sometimes it is confusing if data are coded in a strange way. For instance, the IR data can be detected like SPGR, so the algo is not properly initialize...

Hello, Yes, It's possible but the "Generic Diffusion Importation" will be available with the next release. However, you can do it manually by using commande lines. I advise you to read the documentation of "Diffusion" Module to understand how diffusion data are organized and to k...

Hi,

Today we don't have a better solution. In fact, the downloading of the new driver is a good idea because it can fix the bug if it is a bug of the chipset.

Hi, 1) Is there a way to correct distorded EPI by means of an additional fieldmap images (double echo magnitude image + complex image from Siemens scanner)? 2) if yes, is it possible to correct for geometric distortions related to susceptibility artefacts (mainly for EPI)? I don't know, I'm going to...

Hi Julien, This process is specific to functional MRI. Some fmri processes are added in BrainVISA for pre-processing steps. I never try this one. But I suppose it is ok. You should import fmri data, and use processes in "Functional -> Distorsions ". The importation steps are mandatories. I...

It's ok.
I asked to Muriel by email and I sent the file to Frederica.

Hi , I am very surprising that you have the Multiple Tracking Process because it seems to me that it is only in the developpement package. Perhaps do you have a specific package ? This file (text file, I believe) allows to sample the space with a lot of vestors. Can you describe your diffusion data ...

Hi,
