I have run mri_segstats --seg .../my-glm.wls/group.diff/cache.th13.neg.sig.masked. nii.gz rh parc --i subj/fc.seed.surf.rh/R_seed/z.nii.gz --sum summaryfile
and I have obtained 9 columns and 5 rows. I'm confused on results. Where is the mean z-score for cache.th13.neg. sig.masked.nii.gz? # ColHeaders Index SegId NVoxels Volume_mm3 StructName Mean StdDev Min Max Range 1 -4 7 7.0 Seg-004 -2.4544 0.5023 -3.2164 -1.7619 1.4545 2 -3 153 153.0 Seg-003 -2.6662 1.4724 -6.2120 1.7587 7.9707 3 -2 848 848.0 Seg-002 -2.4930 2.0088 -6.4504 2.3528 8.8032 4 -1 1518 1518.0 Seg-001 -2.1416 1.6727 -6.4227 2.5420 8.9648 5 0 161316 161316.0 Seg0000 1.4152 1.6218 -7.0471 14.1452 21.1923 Because my data are on surface mri_surfcluster should be helpful?
