How do you define the clusters? You can use mri_surfcluster to define clusters, and it can output annotations. You can also use mris_label2annot if you have clusters defined as labels.

Dear FS experts
We would like to transform the sig.mgh file to an annotation file in order to extract the thickness value in each individual brain.
The problem is that we have 3 clusters in the sig.mgh file and we would like to split these 3 clusters into annotations in order to compute cortical thickness within each single cluster.
How to do it?
Thanks in advance Regards Jürgen
