[Freesurfer] Segmentation fault with mri_ca_train
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? -MP ___ Freesurfer mailing list Freesurfer@nmr.mgh.harvard.edu https://mail.nmr.mgh.harvard.edu/mailman/listinfo/freesurfer The information in this e-mail is intended only for the person to whom it is addressed.

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