Folks:
We're wondering about how FS's "folding index" corresponds to Van Essen's calculation (J Neurosci, 1997 Sept 15).
In particular, do the FI values for each region factor out the area of the region or not. When we plot them the FI values look extremely correlated to area, but that doesn't make sense for an index.
Ultimately we're wanting to know how to aggregate FIs for individual parcellations into larger regions.
Thanks,
Graham
