Dear Bruce, I have tried running mri_ca_register again twice with the following cases: Case 1: on VirtualBox with 9.2GB available free disk space. I gave 1GB RAM to this Virtual Machine. Case 2: on Ubuntu installed on a machine with 2 core Dual 2.5Ghz , 4G RAM, and 6GB free disk space. In both cases, I have got the same result as described in the previous mail: segmentation fault. Would you have any suggestion for this problem? Thank you. Bests, Long

Dear Freesurfers,
I have had a problem when running recon-all on your tutorial data (bert). Please find following the content of recon-all.log:

I suspected that the problem occurred at ?mri_ca_register? and reran it as following:
*mri_ca_register -align-after -nobigventricles -mask brainmask.mgz -T transforms/talairach.lta norm.mgz $FREESURFER_HOME/average/RB_all_2007-08-08.gca transforms/talairach.m3z*
It said the following at the end of the process and ?talairach.m3z? could not be found in dir ?transforms/?

Here is what given by ?bugr? command:

I am running the VirtualBox Ubuntu version.
I have looked at previous posts but have not been able to figure out an appropriate answer to my problem. Any of your help would be highly appreciated.
Thank you.
Kind regards,
Long
