Dear Freesurfer experts,
I have a surface parcellation (annotation) with 318 labels; see attachments for each hemi. I wish to extract volume-based features (FA and MD) corresponding to these 318 labels. I believe I should perform something like surf2vol to extend the labels into FA space. However, my surface parcellation is not a surface overlay (which I need for --so). Any other ways to do this?
I wish for the output to be a single volume-based parcellation of 318 labels, corresponding to the two surface parcellation annotation files. I will then use this output to get FA measures for each of the 318 regions.
Thank you, Ellen
