Dear all,

please would you advise if there is any tool in BioC that could help with  the visualization of CHROMATIN INTERACTION NETWORKS as a GRAPH (where NODES="chromosome loci", and EDGES = "interactions").  Thanks a lot !

While this isn't my forte, I thought I'd respond here to your offline message, just in case anyone else cares:

library(InteractionSet)
example(GInteractions)
anc <- anchors(gi, type="both", id=TRUE)

library(igraph)
G <- make_graph(rbind(anc$first, anc$second),
    n=length(regions(gi)), directed=FALSE)
plot(G)

... or see ?layouts for the available graph layouts.
