A PyTorch implementation for the ICLR paper:
Encoding Unitig-level Assembly Graphs with Heterophilous Constraints for Metagenomic Contigs Binning [OpenReview]

UnitigBIN consists of two main components: Learning, which uses a graph neural network to model the unitig-level assembly graph while adhering to constraints, and Binning, a contig-level framework. In the Binning stage, a Matching algorithm is employed to initialize markered contigs, Propagating labels are used to annotate unmarked contigs while satisfying constraints, and a local Refining strategy is incorporated to fine-tune binning assignment.
