Thanks for your answer. For the slice with white matter lesion, I need to manually fill the ventricle. Am I right? Do I need to fill the ventricle in the slices that I don't edit anything at all? Thanks, Antao > -Original Message- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED] Beh

Sarah: Freesurfer surface file formats are documented at: http://grahamwideman.com/gw/brain/fs/surfacefileformats.htm ... including the "W" file format (scroll down). The coordinate system for FreeSurfer's vertices is RAS, described in more detail at: http://grahamwideman.com/gw/brain/fs/coor

Hi Brian, I read in a surface file and it spit out 3 coordinates, do you know if they are RAS and also there is no vertex number with them, so does the vertex number start at zero and count up then? they are RAS coords. surface vertices go from 0-> nverts matrix(in matlab) will go from 1-> nve

Hello, Does anybody know if there is a file with or a way to obtain a mapping of the vertex number with say the RAS coordinate system. I know when you are in the tksurfer window by using the mouse/cursor you can see each vertex number with the corresponding RAS coordinate, but is there a way
