Dear Magno,

Thanks. We are working on an updated manual for the fMRI tool to describe the functional connectivity tools, hopefully this will be out in the next week or so and will describe things in more detail. Intrinsic Connectivity effectively computes the correlation (there are some abstracts from our group describing this and is similar to a recent paper by Buckner et al) from each voxel to each other and then for each voxel counts how many voxels had correlation above a certain threshold (typically 0.25) to compute a degree measure which is then normalized.
