I did some looking and folks don't seem to be happy with how the force-directed layouts in igraph handle negative weights. Often the examples i saw only had a few nodes, so i think we should see how it goes with our networks and modify if needed.
If we do need to modify, one fun idea would be to have options for force-directed: positive only, negative only, both, or absolute value. Basically ways to keep all the edge weights on one side of 0 (except the "both" option). Kathryn was talking about how she's actually only interested in negative edges for the wgcna stuff, which led me to think about this plan.
