Got it. Thanks for the prompt answer! By the way, I tried mri_segstats with --accumulate flag, but it says option '--accumulate' is unknown. I don't seem to find it when I looked up mri_segstas --help either. On Tue, Jun 11, 2013 at 5:05 PM, Douglas N Greve wrote: > > Right, so in this case, th

Hi Doug -- I copied and pasted the summary file below. It looks like mask.mgh was treated as volumetric image. Also I'm not sure how to interpret TableCol. # Title Segmentation Statistics # # generating_program mri_segstats # cvs_version $Id: mri_segstats.c,v 1.75.2.2 2011/04/27 22:18:58 nicks E

[Freesurfer] How to measure the surface dimension in a mask image after mri_glmfit?

2013-06-10 Thread Glen Lee
Dear freesurfer users I'm wondering if there is any way of figuring out the surface size within a mask image (mask.mgh) which is generated after running a group-level GLM analysis (2nd RFX) using mri_glmfit. As I'm thinking, this may be: number of vertex by dimension of one vertex (1mm). But I
