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?

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. doug On 10/03/2016 12:35 PM, Josue Luiz Dalboni Da Rocha wrote: > > 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?
