Registration of freesurfer files with preprocessed functional data?

[SylvainTakerkart]

Hi there!

We're working on surface-based analysis of resting-state data from ABIDE. So whttps://github.com/preprocessed-connectomes-project/abide/issues/18e're trying to use freesurfer's full output directory that we were able to download together with the preprocessed functional data in order to project the functional data onto freesurfer's meshes... (before doing whatever we'd like to do on the surface ;) )

However, the preprocessed functional data is in MNI space and it seems freesurfer's recon-all has been run in the subject's native space. So the two are not aligned and we cannot project directly the functional preprocessed data onto the surface...

So how would you do it? One of my ideas was to try to get the transformation "Anatomical2MNI" files that have been estimated to put the functional data into MNI space, to perform the inverse transformation in order to put the functional data back into native space (if possible), but I cannot find those transformation files... Are they available somewhere? If not, how would you do it?

Thanks for your help,

Sylvain
