I have a question regarding the parcellation of the rat cortex. I am interested in parcellating the cortex into distinct regions using an atlas and then finding grey matter volumes for each region. I realize that Freesurfer is primarily meant to be used on human subjects, but is it possible to replace the MNI atlas with a rat atlas (like the LONI rat atlas) during the parcellation step? Thanks for your time and help.

best wishes,

Mike
