Description
This assembly of IG 72805 (Lens tomentosus) was constructed with long-read data (60x Oxford nanopore reads). The contiguity of the assembly was further validated and improved using HiC data and a genetic map (LR-90; IG 72614 x IG 72805 intraspecific F2). The finished assembly is 4.07 Gb arranged in 7 pseudo-molecules and 1093 unplaced unitigs (97.8% anchored).

Analysis Method
Using the GenomeFocus workflow, long reads were assembled with smartdenovo and polished with racon. Due to the high degree of telomere tethering observed in Lens species, a genetic map (LR-90) was used to form the initial clusters for HiC data incorporation. ALLHiC is then used to order and orient contigs within each pseudomolecule cluster. Any corrections and a final manual check are made with Juicebox.
