Hi Olivier, I am not sure that I completely understand what you have in mind. Normally, we do this kind of operation using Anatomist, not brainVISA. By default the AnatomistShow... turn on all the sulci, because it was clearer behaviour for most of the user, but afterwards, using the hierarchy of su...

Hi Nicolas, nobody dares to dive into that part of Anatomist here except Denis. Therefore you will have to wait to get an answer except if you dive yourself. I know you already had a nasty experience with this part of the code which is pretty confusing (its history involved several people). However,...

Unfortunately, Anatomist seems to save the normalized data rather than the initial one. Unfortunately, D. Rivière is skiing somewhere in the Alpes for two weeks...

Distortion correction

Hi, brainVISA currently includes a process to correct for eddy current induced distortions in DWimages (as long as your encoding direction is the same as ours, otherwise there may be some flipping operations to add). No additional data is required (a paper on our site describes the method). The EPI ...
