Hi
We were able to extract the vertex number (and MNI coordinates) for the
finer parcellation as well as for the aparc.a2005s parcellation by using
mri_annotation2label. Now we have a .label file for each parcellation  
where
all vertices number (and their coordinates) that belong to a  
parcellation
are listed.

Do you have any suggestion or idea how to match the vertex number for  
both
parcellations in order to get the anatomical labels for the finer
parcellation?

Kind regards
Diana
