[Freesurfer] Gray matter volume calculation

2017-05-30 Thread Josue Luiz Dalboni Da Rocha
Dear Freesurfer team, We are analyzing the gray matter volume of some customized labels, using mris_anatomical_stats. We are wondering about some characteristics of the obtained volume. Is the volume of a label (as calculated by mris_anatomical_stats) the sum of the volume elements of each

[Freesurfer] White matter volume of a costumized Gyrus

Dear Freesurfer team, I am working with calculated volumes of a gyrus (a costumized label). I currently use mris_anatomical_stats to calculate the volumes of my gyrus (in label format). According to the freesurfer tutorial (as I understood), one of the stats outputted from

Dear Douglas, I have a segmented gyrus curvature file (.curv or .w) and I would like to calculate the volume (and other statistics) of this gyrus. I currently only know mris_anatomical_stats to perform that, but requiring a '.label' file. Can I extract statistics directly from the ".curv"
