Thanks very much for getting back so quickly. Please pardon. I’m sure this answer must be in lots of other places.

Use mri_diff (volumes, segmentations, and surface overlays) or mris_diff for surfaces to check whether they are different.

To do so we are comparing identically named files using md5sum and would very much appreciate your thoughts on our results. For multiple files, we concatenate them and pipe the output into md5sum. Below is a table showing what we’ve found so far. I take hope from the positive matches we get from all of the .annot files and from the fact that 001.mgz does not match. This latter suggests that there is a date or something embedded in some of the files from separate runs which defeats the match. Please let us know what you know about this and thanks. file(s) md5sum result label/*.annot match label/*.label match mri/wmparc.mgz mismatch surf/qsphere.nofix surf/rh.sphere mismatch mri/orig/001.mgz mismatch mri/transforms/talairach.m3z match mri/transforms/talairach.m3z.inv.x.mgz mri/transforms/talairach.m3z.inv.y.mgz mri/transforms/talairach.m3z.inv.z.mgz mismatch mismatch mismatch Best - Don Don Krieger, Ph.D. Department of Neurological Surgery University of Pittsburgh _______________________________________________ Freesurfer mailing list Freesurfer@nmr.mgh.harvard.edu<mailto: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.
