Dear FS team,

We want to create a ROI based on the wm parcellation in the 2009s atlas. We ran the following command:

mri_aparc2aseg --s <subjid> --labelwm --hypo-as-wm --rip-unknown --ribbon --o mri/wmparc.a2009s.mgz --ctxseg aparc.a2009s+aseg.mgz (<subjid> was replaced by our subject)

We get the following error: option -–ribbon unknown.

The ribbon.mgz folders exist and are located in the right directory. We also tried to re-create them and this worked fine, but again after running the command above we got the same error.

If we changed the command –-ribbon to –- no ribbon, the script ran, but when we looked at the stats-file, only cortical grey matter labels were segmented (no wm).

The same applies to other subjects we tried.

Could you please help us out?

Many thanks.

Jolijn & Caroline
