Hi Freesurfer mailing list,
Using an external software package we have completed of analysis for the vtx-wise thickness data extracted from freesurfer. We now have a p-value array containing one value for each vtx, and we would like to map this back onto the brain surface. Is there a way to create a .mgh overlay from our array of p-values using fsaverage as the subject?
Hi Bronwyn,
sure, it should be easy to do in matlab. If the array is called pvals and it is from the left hemi, you would do:
save_mgh(pvals, 'lh.pvals.mgz', eye(4), [0 0 0 0]);
cheers Bruce
