Dear Bruce,
Thank you very much for your answer!
Can I convert the data from '.curv' to '.label' in order to extract the volume?
What I was trying to do was to convert the '.curv' file to nifti volume (mri_surf2vol), binarize it (mri_binarize), and then convert to label (mri_cor2label). Is it a correct way to extract the volumes from a '.curv' file?
Best regards, Josue

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 <label file> to compute the volume

Dear Douglas,
I have a ".curv" file that contains the curvature information inside an automatically delineated ROI and 0 everywhere else. I would like to calculate the volume of this ROI,
Can I extract statistics directly from the ".curv" file?

What is the nature of the segmentation? Is it just a binary (1=in, 0=out) segmentation? And what file format? In general we don't use .w anymore, but it can be converted into something else.

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" file?
Or can I convert directly from .curv to .label in order to extract these statistics?
As another option, is it feasible to convert the '.curv' file to nifti volume (mri_surf2vol), binarize it (mri_binarize), and then convert to label (mri_cor2label)?
What does the output nifti file from 'mri_surf2vol' contain? Does it contain the complete volume behind the surface? Or does it only contain the surface over the 3D space?
Thank you very much in advance for your help!
Best regards,
Josue
