Re: [Freesurfer] thickness measures

Hi Greg, load the ?h.thickness files in tksurfer as curvature maps or overlays to get the point-wise map of thickness. Use mris_anatomical_stats for the summary stats. You can use the -l option to get summary stats for a region instead of a whole hemisphere. cheers, Bruce On Thu, 3 Mar 2005,

Hi Doug, The data is in: /space/thursday/users/greve The lowb prefixed bfloat volume was the one on which the ROI was drawn on (saved as test.label). If I was to tkmedit this volume, and load the test.label file, everything looks ok. Then, I converted the volume into ANALYZE (using mri_convert)

Hi Doug, Thanks a lot, this almost worked! I have one more issue. The template volume is an axial volume. It was loaded in tkmedit, and the ROI was drawn on its coronal view, and then saved as a label file. After running mri_label2vol the resulting ANALYZE file displays the ROI incorrectly. W

Have you checked the talairach.xfm file? If not, visually inspect it using file->transforms->load transform for main volume to make sure it's right. You can always manually set it with mri_fill -cc . See the FAQ. cheers, Bruce On Thu, 3 Mar 2005, Harshad Shanbhag wrote: Hi all, My earlier er
