We have released version 0.3.0 of LUE. This version contains new flow accumulation algorithms that scale well over CPU cores and cluster nodes, and that compose well with other modelling operations. As the version number shows, LUE is not yet ready for production, but every new release gets us closer to that point. We will release Conda packages including the LUE framework ASAP.
