Many of you may have received pessimism from me over the years about using Hi-C to predict distal regulatory effects, mired with paradoxical optimism that cohesin loop extrusion is key. Well, the story behind all that rambling is finally ready to be told.

Ever wanted to watch chromosomes fold? lefsim simulates loop extrusion live in your browser. Add, remove and drag CTCF sites around, watch contact maps emerge, and more. lefsim.abdenlab.org
