Hello all FS users and experts,

I'm wanting to get the sub cortical segmentation as ASCII files, so I'm trying convert the aseg.mgz into a surface file, to finally get an ASCII file,

For this I'm using the next commands:

First: mri_convert -rl rawavg.mgz -rt nearest aseg.mgz aseg2raw.nii

To preserve  the aseg volume in native space 

Second: mri_vol2surf --mov aseg2raw.nii --regheader mysubject --hemi lh --o ./lg.aseg2raw.mgh
