Hello,

I'm running recon-all on a file and and running into an unfamiliar error. This error has been mentioned previously in the archives with no clear answer (see below for previous emails), and just as in that case, the brainmask.mgz looks reasonable. The recon-all.log is attached. Any idea what is going on? Its failing finally here: mri_ca_register -invert-and-save transforms/talairach.m3z

Loading, Inverting, Saving, Exiting ... Reading transforms/talairach.m3z ERROR: cannot find or read transforms/talairach.m3z ERROR: mri_ca_register with non-zero status 0

Thank you for any and all assistance! Stacey Schaefer ----------------

Hi - Was there ever a solution found for this? I am currently having the same problem. Thanks, Jeff Thompson Can you send us e recon-all.log file?
