RefSeq Drosophila Chain/Net (refseqDrosChainNet) Track Description


	Description Genomic scaffolds from each Drosophila species are aligned against the D. melanogaster genome assembly (dm6) using LAST with default parameters. The alignments are then processed using the UCSC whole genome alignment protocol (i.e. chaining and netting). References Kiełbasa SM, Wan R, Sato K, Horton P, Frith MC.
