Filling Annot Files Into a Volume
This page describes a 2-step process to fill values from an "annot" file to a volume.
Step 1 : Creating a Cortical Ribbon
You need a cortical ribbon in order to create an accurate mask of the ribbon. If the files lh.ribbon.mgz and rh.ribbon.mgz don't already exist in your <subject>/mri directory, then you can create them using ["mris_volmask"]. For instance, if your subject's name is bert, you can run
mris_volmask --save_ribbon bert
Step 2 : Filling the Cortical Ribbon
Once the ribbon files have been created, you can fill the ribbon with values from the desired annot file, using ["mri_aparc2aseg"]. The annot files will have to be in the subject's label directory. If your annot files are lh.myAnnot.annot and rh.myAnnot.annot, then you can run the following command to fill them
mri_aparc2aseg --ribbon --s bert --o bert/mri/myAnnot.mgz
