Re: [Freesurfer] Mapping group fMRI on surface

You mean you want to display your group volume-based results on the average surface? That's unusual, but it can be done. You need to create a registration file between your group average and the standard space templage, eg, something like: fslregister --mov $FSLDIR/etc/standard/avg152T1.nii.

we haven't distributed it yet, but it would just take the form of label maps with associated probabilities in fsaverage space. You would need to do our surface-based averaging for it to apply. We haven't gotten the auditory cortex data yet, but probably could if you were interested. On Tue, 1

Bruce, it's auditory cortex I am interested in. If there is a tutorial or explanation somewhere, could you please point me to it. Is this already available in FS? Thanks Martin On Tuesday 13 November 2007 14:38:52 you wrote: > what areas specifically? We have analyzed their data and have a pape

what areas specifically? We have analyzed their data and have a paper accepted at Cerebral Cortex on the surface-based equivalent atlas, which is quite a bit more accurate than the linear or nonlinear volumetric ones, and are getting ready to release it for general use. cheers, Bruce On Tue, 1

Hi, I can not find my way to map the results of the FSL fMRI group analysis (FLAME1+2) from different subjects on their average surface. Here is in more details what I have done: 1. fMRI analysis of each subject in FSL 2. group analysis (FLAME1+2) in FSL 3. cortical reconstruction of each subje
