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" f
0=out) segmentation? And what file format? In general we don't use .w
anymore, but it can be converted into something else.

Hi Josue
the *.curv won't help you with the volume. If it is a label file you
should be able to give it to mris_anatomical_stats with -l to
compute the volume

I would binarize the curv file with
mri_binarize --i lh.yourcurvfile --abs --min .001 --o
lh.yourcurvfilebin.mgh
Then compute the volume with
mri_segstats --seg lh.yourcurvfilebin.mgh --id 1 --i lh.volume
--accumulate --sum lh.vol.yourcurv.sum

How did you create the label ?

Dear Doug,
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

According to the freesurfer tutorial (as I understood), one of the stats

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 v

Dear FreeSurfer,
Why an average whole hemispherical value for mean curvature is not provided by
Qdec?
Is there geometrical reason?
Best regards,
