[Freesurfer] Problem with cortical GM vol
Dear FreesurfersAs recommended I'm calculating the cortical GMWM vols from the surfaces. Using the --excl-ctxgmwm to exclude the GMWM volume from the segmentations and the --surf-ctx-vol and --surf-wm-vol to respectively compute the GM and WM surface volumes. The problem is that in the aseg.stats file the lines:# surface-based-volume mm3 lh-cerebral-white-matter # surface-based-volume mm3 lh-cerebral-cortex # surface-based-volume mm3 rh-cerebral-white-matter# surface-based-volume mm3 rh-cerebral-cortex are not appearing, I've checked with the volumes using mris_volume -v lh/rh.pial and mris_wm_volume subjID lh/rh -v. Only the volumes from the mris_wm_volume coincide with the ones in the ones in the lines: # Measure lhCorticalWhiteMatter,.,Left Hemisphere Cortical White Matter Volume, ,mm3 in both hemispheres but not the cortical GM volumes-- --PhD. student Gabriel González-EscamillaLaboratory of Functional NeuroscienceDepartment of Physiology, Anatomy, and Cell BiologyUniversity Pablo de OlavideCtra. de Utrera, Km.141013 - Seville- Spain -Email: ggon...@upo.eshttp://www.upo.es/neuroaging/es/ ___ Freesurfer mailing list Freesurfer@nmr.mgh.harvard.edu https://mail.nmr.mgh.harvard.edu/mailman/listinfo/freesurfer The information in this e-mail is intended only for the person to whom it is addressed.

[Freesurfer] Problem with cortical GM vol (complete)
For some reason I'd send the las e-mail unfinished, here's the complete one:Dear FreesurfersAs recommended I'm calculating the cortical GMWM vols from the surfaces. Using the --excl-ctxgmwm to exclude the GMWM volume from the segmentations and the --surf-ctx-vol and --surf-wm-vol to respectively compute the GM and WM surface volumes. The problem is that in the aseg.stats file the lines:# surface-based-volume mm3 lh-cerebral-white-matter # surface-based-volume mm3 lh-cerebral-cortex # surface-based-volume mm3 rh-cerebral-white-matter# surface-based-volume mm3 rh-cerebral-cortex are not appearing, I've checked with the volumes using mris_volume -v lh/rh.pial and mris_wm_volume subjID lh/rh -v. Only the volumes from the mris_wm_volume coincide with the ones in the ones in the lines: # Measure lhCorticalWhiteMatter,.,Left Hemisphere Cortical White Matter Volume, ,mm3 in both hemispheres but not the cortical GM volumes.In fact for GM the volumes are: aseg.stats lh=156531.224634 rh=153692.917345mris_volue lh=436143.018321 rh=444925.772579Which as you may see are completely different, the sum from the two from the aseg are not even close to a single from the mris_volumeIs there any way to know which volumes are correct?and how can I calculate this to appear on my aseg.stats? or any other text fileMany Thanks in advanced,Gabriel ___ Freesurfer mailing list Freesurfer@nmr.mgh.harvard.edu https://mail.nmr.mgh.harvard.edu/mailman/listinfo/freesurfer The information in this e-mail is intended only for the person to whom it is addressed.
