Hi Noam, these seem to be corrupted in a way that makes it so only freesurfer 5 can read them. If you source 5.3 and 'resave' the vols with mri_convert, like:
mri_convert aseg.mgz aseg.mgz
That should fix whatever the problem is and allow you to load them in v6+

Dear group, When trying to run mri_pretess, I'm getting this error: znzTAGskip: tag=809120822, failed to calloc 1802706944 bytes!
Cannot allocate memory
Here is the full command I'm using (in the Martinos center, using ver6 stable):
mri_pretess /autofs/space/thibault_001/users/npeled/subjects/mg27/mri/aseg.mgz 54 /autofs/space/thibault_001/users/npeled/subjects/mg27/mri/norm.mgz /autofs/space/thibault_001/users/npeled/subjects/mg27/tmp/274f23/54_filled.mgz
Thanks! Noam
