Hi Syeda

Hello Freesurfer experts,

I'm getting a segmentation fault when I use the mri_label2vol command to push aseg labels from freesurfer space to my subject's original T1 space (using the example given on the freesurfer website). I'm not sure why this is happening...I've tried changing the parameters countless times but nothing has worked. I also checked my "aseg.mgz" to make sure it's not corrupted but that isn't the issue either. Any help would be highly appreciated!! Thanks in advance
