Hi FreeSurfer List Is their any way that I can generate cortical and sub-cortical volume masks by using the surfaces generated by FreeSurfer. If I can could anyone give me the proper command. Apparently, The masks I already generated using mri_binarize command, are little bigger and spilling into the surrounding. Thank you in advance, Truly, Indika Walimuni Research Associate University of Texas Health Science Center Houston, TX.
