Hello Thorsten,

Sorry for the late reply.

I think that the analysis that you propose is valid.

I did not look at consistency across different populations, but this is a very interesting thing to do.

The size of an ROI and its overlap with regions of other atlases will depend on size, but you can still attribute clusters to functional networks. For example you could assign regions to networks derived in Yeo and Buckner 2011 by amount of overlap.

I hope these help!

Cheers,
Cameron
