Hi Bruce, In both versions, I use this command: mris_flatten rh.occip.patch.3d rh.occip.patch.flat
They are applied to the same patch. Also may be I missed it but when I used help (mris_flatten --help) I didn't see any of these flags.

You can remove the randomness by either specifying -norand or using a specific seed like -seed 1234. That said, you second image looks like a failure of the flattening. This usually means the distances aren’t sampled out far enough/densely enough. The defaults are super old (7 neighbor ring, 12 distances/ring). You could try something like -distances 20 20 and see if that fixes things (and -norand if you want) Cheers Bruce From: freesurfer-boun...@nmr.mgh.harvard.edu <freesurfer-boun...@nmr.mgh.harvard.edu> On Behalf Of Nasr, Shahin,Ph.D. Sent: Friday, April 7, 2023 3:15 PM To: Freesurfer support list <freesurfer@nmr.mgh.harvard.edu> Subject: [Freesurfer] mris_flatten Version 6 vs. 7 External Email - Use Caution Hi Surfers, This is the second time that I have brought this issue up. When applied to the same 3D patch, the command mris_flatten generates two completely different outcomes when runs under stable 6 vs. 711 (see the attached files). I checked the documentation if there is any flags by which I can control the process. But I couldn't find anything relevant. Any idea what has happened? Regards Shahin Nasr, Ph. D.
