Yes, that is correct

Dear Doug,
*--sumwf * seems to work fine - it gives subjectwise values and values seems of to be of volume:
11262.26605 9294.07182 12673.14610 12601.33416 11141.31917
....
....
Whenever you get a chance, could you please confirm if --sumwf is the correct flag here?
Thanks.

Dear Doug, Yes, that gives me subjectwise values if I run the following command, but now the output doesn't seem to be the volume values, it gives very small subjectwise values as following: mri_segstats --seg lh.HC_GAD.vol.glmdir/p_bin.mgz --excludeid 0 --i lh.HC_GAD.vol.10.mgh --accumulate --avgwf volumesum1.table Output: 1.49360 1.71227 1.84950 1.58922 1.98355 1.49314 1.37157 1.77108 1.87064 2.08438 1.87076 1.61026 2.42607 1.69756 1.65158 1.61560 On Wed, Sep 30, 2020 at 12:58 PM Douglas N.

I created a binary mask and ran the following command, but the output gives me only one value of volume as follows.

To: Freesurfer support list <freesurfer@nmr.mgh.harvard.edu <mailto:freesurfer@nmr.mgh.harvard.edu>> Hello everyone, I have significant group differences in volume (controls > patients) for one of the clusters (say C1) - calculated after permutation test using PALM, which gives me following outputs: *_clustere_tstat_fwep.mgz (this is significant at p < 0.05, number of voxels = 1105) *_clustere_tstat.mgz *_dpv_tstat_fwep.mgz *_dpv_tstat_uncp.mgz *_dpv_tstat.mgz I was wondering if there is a way to calculate volume values of C1 for each subject (i.e., controls and patients).
