Hi Mark
have you tried "conforming" the inputs (making them all 256^3, 1mm iso
and 8 bits/voxel)?

Hello freesurfers,
I am running into some sort of memory allocation issue when running
mri_ca_train. I am
simply using an intensity volume and a segmentation volume to create a GCA
atlas. I keep
getting this "segmentation fault: 11", which is data allocation error. I have
tried using all
different environments and can't avoid it. The output is below:
sh-3.2# mri_ca_train -T1 withSkull.mgz -seg seg_edited.mgz atlas_test
/hearingbrain/Desktop/atlas_withSkull.gca
reading T1 data from subject's mri/withSkull.mgz directory
reading segmentation from subject's mri/seg_edited.mgz directory
training on 1 subject and writing results to /Volumes/Macintosh
HD/Users/hearingbrain/Desktop/atlas_withSkull.gca
***************************************************************************
processing subject atlas_test, 1 of 1...
reading input 0:
/Applications/freesurfer/subjects/atlas_test/mri/withSkull.mgz
gca width modified from 256 to 181
gca height modified from 256 to 217
gca depth modified from 256 to 181
Segmentation fault: 11
Any ideas?
