External Email - Use Caution Hi, Tim,
the subject ID can be also contained in the commandline history which is stored in .mgz files. This can be viewed using mri_info file.mgz --cmds I am not aware of any direct command which can strip out this info, but you surely could convert .mgz file to .nii and then (using path which does not contain subject ID) convert back to .mgz, if needed. Antonin Hi Doug,thanks for the mri_add_xform_to_header idea, I didn't know about that option!
