Hi Don
are you saying the 001.mgz is different when created from the same dicom
data? Can you run mri_diff on it to see what the difference is?
cheers

We would like to confirm that we are getting identical results from multiple
freesurfer runs on the same data set.
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.
