Bipartite connectivity mapping (BCM)

The program vbcm implements a new approach for analyzing connectivity in rs-fMRI between two brain regions. The two regions can be of any size, but should be non-overlapping. The main idea is to represent connectivity between the regions as a bipartite graph and analyse it using bipartite network projections. The advantage of this approach is that it allows to fully preserve spatial precision in both ROIs. This sets it apart from traditional seed-based connectivity mapping where the seed ROI must be averaged so that its spatial information is lost.

Example:

vbcm -in func.v -roi1 roi1.v -roi2 roi2.v -out result.v
