Hi! I am trying to make a ribbon.mgz from a non-human primate surface recon that does not have an aseg. Following this prior discussion: Re: [Freesurfer] ribbon.mgz Without aseg.mgz (mail-archive.com) https://secure-web.cisco.com/1ak2oe-adeCSsLNqdcSfpPz47btc0Bg4_-64m15yi4A3arakBiE7rQ-e9Ic--HcZjzBr8owRBFUicdouc7e2zl78qnX0T7FnwdllHDGAeM_4lAB6y3cenwxCzUG3lomlWl7BjXQbs4PesuZet8wvOXyZgrU9ePd4D9fZQEHvmpLBuI3G_a9NjVljMypuSefd0w8HYbmqeeqk3V6FQctpxtYq7VxlSRohysbd2HtGet4ulmKNUGr16_yWQ5tGzBFans_D-RTGtinwVa8sbtjRjqg/https%3A%2F%2Fwww.mail-archive.com%2Ffreesurfer%40nmr.mgh.harvard.edu%2Fmsg21349.html I tried mri_ribbon:
mri_ribbon ./surf/rh.white ./surf/rh.pial ./mri/orig.mgz rh.ribbon.mgz
Attached is the output. It looks like it roughly follows the grey matter, but especially the sulci seem to be filled. Unfortunately, there is no help for mri_ribbon. Any advice on how to proceed? The above mentioned discussion did not lead to a conclusion on how to get a ribbon without aseg. Thank you! Caspar
