mris_volmask can't work with my data ( error: mghRead(/data/fmri_monkey_raw/fs/subjects//thelma_anat5/mri/aseg.mgz, -1): could not open file), we can't with the anatomical images we have proceed to the regular segmentation, we skip automatic segmentation because it wouldn't work for monkeys. So, i suspected i must use mri_surf2vol, my problem was that i don t understand which file i should use, how i put the command even using mkmask, i don't understand which inputs, what the command need to have what i really want. Sorry, but i'm a bit confused i'm used to use mri_vol2surf or mri_label2surf, but here, i m not able to find exactly what the command need to work Best regards, Sherihane Bensemmane PhD Student, Research Group Neurophysiology, K.U.

if i use mri_surf2vol on the pial alone, i would have the entire gray matter?

you can try mris_volmask or mri_surf2vol. volmask is the better choice if it works for your data. Look in recon-all to see how to call it. This is what creates the ribbon.mgz file, which sounds like what you need

Hi, I am using freesurfer for non_human primate. I did the segmentation in freesurfer , at the end i have the wm.mgz but not grey matter since the command to get it during segmentation doesn't work in monkey brain. in the forlder /surf/ i have all files such as lh/rh.pial, curv, sulc, white. Since I am also using SPM and some toolbox to conduct my connectivity data i need good segmentation, so i wanted to use the files in surf, the pial and white to get the grey matter information and then convert it to a volume file. I've been looking for solutions, but didn't find anything, can you help? how shall i proceed to get my grey matter mask from my segmentation, in the native space.
Thank you,
