It is giving you values for two segmentations: inside the label and outside the label. Use --id 1 to get only values inside the cortex labelOn 9/9/2020 11:27 AM, vittal korann wrote:

Dear FreeSurfer experts
I am working on the gyrification index of schizophrenia patients. I had collated global brain values such as thickness, GM, and WM volumes. In addition, I wanted to tabulate gyrification values. Using the below link I was able to extract the hemispheric mean gyrification values.MailScanner has detected a possible fraud attempt from "secure-web.cisco.com" claiming to be https://www.mail-archive.com/freesurfer@nmr.mgh.harvard.edu/msg31829.html
But it is giving me 2 rows of output that are adding more ambiguity to the existing problem. Below is the command which I used to get mean gyrification for the left hemisphere and also the corresponding output. *Command Line: *
mri_segstats --slabel CSRI104 lh
/usr/local/freesurfer//subjects/CSRI104/label/lh.cortex --i
/usr/local/freesurfer//subjects/CSRI104/surf/lh.pial_lgi --sum
lh.aparc.pial_lgi.stats *Output: *
# NRows 2
# NTableCols 10
# ColHeaders Index SegId NVertices Area_mm2 StructName Mean
StdDev Min Max Range
1 0 6879 4687.8 Seg0000 2.4509 0.2838
1.8067 2.8873 1.0806
2 1 128054 84259.7 Seg0001 3.0148 0.6366
1.9369 4.7611 2.8242 My confusion is that which row I should take it as a mean gyrification value for the left hemisphere (seg0000 or seg0001)?Please guide me if there is a way to combine two hemispheric values and make it as mean gyrification alike mean thickness.With regards
Korann

I am trying to extract the mean gyrification values for the whole
brain alike cortical thickness.
We have all the whole-brain parameters in 'aparc.stats' file. But
we do not have one for the gyrification index. Is there a way to
do it?
Would be grateful for your help.
Best
Korann
