These are probably rookie questions. 

1. I can read an .annot file with read_annotation.m, is there a way to write one? (for example read it to matlab, modify, and save, or create a combined (lh+rh) aparc.annot file etc. 

2. On the same line, how one combines all the Brodmann labels into a Brodmann parcellation, if not done already..

Thank you,
