Hi list,

a) I have two maps, one's of rs-fMRI functional connectivity (by FS-FAST) and one's of receptor density (from a PET-Atlas). Both the maps are in surface space. How can I measure the vertexwise correlation between the two maps?

You can use the per-vertex option (--pvr) in mri_glmfit. Search through the mail archives to find how to use it

b) How can I move some atlases in volume (MNI) to surface? I have tried to use:

mri_vol2surf --src ATLAS_vol.nii --regheader fsaverage --projfrac 0.5 --hemi lh --out ATLAS_surface.nii

but the results are inconsistent.

Probably easiest to just run recon-all on the MNI152 volume, then map it to that output

Thanks

Stefano
