Hi all,
I am trying to transfer a surface file from fsaverage_sym space to a recently edited individual subject's hemisphere. I previously ran recon-all on the subject and then edited the wm, brainmask, etc. to fix some defects I had found. Before the edits, I could transfer the surface and load it on the subject's hemisphere as an overlay perfectly fine. After editing and rerunning the subject through recon-all and the xhemi pipeline, I tried to transfer and load the overlay again using the following command, same as originally:
mri_surf2surf --srcsubject fsaverage_sym --srcsurfreg sphere.reg --trgsubject subj001 --trgsurfreg fsaverage_sym.sphere.reg --hemi lh --sval template.sym.mgh --tval subj001/surf/template.sym.mgh
The command completes, but the resulting overlay does not have the same number of vertices as the surface. It does however, have the same number of vertices as the original surface from before rerunning the recon-all command. So it seems like it's still transferring the overlay to original surface. My SUBJECTS_DIR does not have the subjects' original recon-all data in it either, just the data from the edited recon-all. Any help on this would be appreciated. Thank you!
