OCN = output cluster number. Each vertex gets a value, that value is the integer number of the cluster number the vertex belongs to (or 0 if it does not belong to a cluster). It is basically a segmentation. For visualization, the .annot file is probably better. You might not have seen anything because nothing may have survived correction or because the threshold was too high doug

Dear FreeSurfers,
I obtained a file from cluster analysis, called "cache.th20.pos.sig.ocn.mgh"
Can you tell me what OCN stand for? And what is this file for? I tried to view it but was unable to see anything.
Best, Daniel
