You can create a ribbon volume with the command below:
mris_volmask \
--label_left_white 2 --label_left_ribbon 3 \
--label_right_white 41 --label_right_ribbon 42 \
--save_ribbon --save_distance youraveragesubject
Note this when you make the aparc+aseg in this way, it should only be
used when visualizing data on the mni305 brain. Don't extract volumes,
etc. If you want to use one of the surface parcellations, do a
surface-based analysis.

Hi,
When I use make_average_subject to generate an average data, I can't find
aparc.a2009s+aseg.mgz within the new average/mri. To get common parcellation
to all subjects, I need to create this file. I understand that "
mri_aparc2aseg --s average --a2009s
" enable to perform what I want. However, when running this command, a error
message shows up "ERROR: cannot find
/drive3/Stammer/Thickness/average/mri/ribbon.mgz". As displayed by this
message, I did not find the ribbon.mgz file. I don't konw how to figure out
this problem. Any suggestions?
By the way, my make_average_surface file is updated by Nick's new one. And
it does not include ribbon.mgz before updating.
