Hi,

I'm trying to deface an MEMPRAGE dataset using the following command:

[jazz:test_deface] (nmr-stable53-env) mri_deface outSubDir/mri/orig/001.mgz  talairach_mixed_with_skull.gca face.gca sample_T1_input_defaced.mgz

and am getting the output:

logging results to sample_T1_input_defaced.log
reading 'talairach_mixed_with_skull.gca'...
reading 'outSubDir/mri/orig/001.mgz'...
changing type of input volume to 8 bits/voxel...
MRIchangeType: Building histogram 
Segmentation fault (core dumped)

I'm using the Martinos center's default version of mri_deface located at /usr/local/freesurfer/stable5_3_0/bin/mri_deface. I'm using the talairach_mixed_with_skull.gca and face.gca sample files found onhttps://surfer.nmr.mgh.harvard.edu/fswiki/mri_deface but the actual input mgz came from a scanner here at the center. Maybe this is a CentOS 7 compatibility problem? Please let me know if there is any other information I can provide.

Thank you,

Graham
