Dear List,

I have run recon-all –all on the same scan on two different machines likely running two different versions of Linux but in any case the runs were done with different numbers of cores.

I  haven’t done anything fancy to compare that the results are identical except for some spot checks of individual files with md5sum.

label/lh.BA4a.label shows up the same on both.

mri/wmparc.mgz does not.

Your comments would be welcome.

Is there something about the non-ascii files, e.g. wmparc.mgz, which would make them show different checksums, e.g. inclusion of a processing time or some such?

Do you have experience or suggestions for convincing ourselves that we are getting the same answers on different machines?

???

Thanks - Don
