Re: [Freesurfer] pial surface question

2007-04-20 Thread Bruce Fischl
Hi Jess, I agree with Jenni. It looks like it missed some of the white matter, which is why it also didn't get the pial surface. Was the wm.mgz accurate there? If it was, then the problem is probably the topology fixer. If not, then putting control points in the white matter would be my sugge

Hi, I am new to FreeSurfer and even after having read the wiki, I have a few questions regarding the coordinate systems. 1. What coordinate system do the final surfaces have. ie. mris_convert rh.pial rh.pial.ascii will list the coordinates in what space? 2. Are the coordinates of T1.mgz and rh.p

[Freesurfer] calculation of total cortical gray matter volume

2007-04-20 Thread Michael Harms
Hello FS-list, Could you please confirm the recommended current approach for calculating the total cortical gray matter volume. Based on the following Wiki page http://surfer.nmr.mgh.harvard.edu/fswiki/MorphometryStats? action=highlight&value=mris_volume I presume that the recommended calculatio
