External Email - Use Caution Dear Doug,
Thanks for your response. I created a binary mask and ran the following command, but the output gives me only one value of volume as follows. I was wondering how I can extract the values for each subject. mri_segstats --seg lh.HC_GAD.vol.glmdir/p_bin.mgz --excludeid 0 --i lh.HC_GAD.vol.10.mgh --accumulate --sum volumesum.dat ..... ..... # ColHeaders Index SegId NVoxels Volume_mm3 StructName Mean StdDev Min Max Range 1 1 6126 6126.0 Seg0001 11262.2666 0.5353 0.9159 3.4016 2.4857 On Wed, Sep 30, 2020 at 9:17 AM Douglas N.
