I am trying to resample some surface overlays from fsaverage to fsaverage_sym

You would do that through the subject’s own surface. It does not work very
well to map data directly from the volume onto group average surfaces (see e.g.

Dear experts,
I posted a message last week about converting NIFTI files into GIFTI format,
then GIFTI to CIFTI, whilst keeping these functional data in the same space as
the subjects FS surface. I got some information RE usign the HCP workbench, but
for this purpose and I don’t know
what level of compatibility there is with CIFTI in FreeSurfer currently.
Perhaps one of the FreeSurfer developers can comment more on that.

Doing sICA on that
will potentially be more computationally intensive than on the original volume
given the upsampling; however. I wonder if it would be better to resample the
sICA maps computed in CIFTI standard space back to the native FreeSurfer mesh
based on the ciftify output?
an have standard meshes in subject’s
physical space and FreeSurfer original meshes in MNI space.

careful about the one-based indexing in matlab. That is, if your ROI is in a
label file and you read the vertex indices from it, you need to add 1 to the
index that point into the overlay.
