Drosophila species genome assembly statistics

Figure 1 shows DNA coverage of species assemblies to D.melanogaster genome, size of species assembly and counts of inverted segments. Coverage for earlier assemblies(asm1) along with latest assemblies are shown. Dmel asm1 size includes heterochromatin; only euchromatin was used for DNA matches.
Figure 2 shows DNA coverage as percent of D.mel. chromosomes.
Figure 3 shows inverts to the D.mel. chromosomes. Inverts are counted as changes in strand within each scaffold, so are affected by completeness of assembly as well as genomic inversions. Matches are made with BLASTn of genome assembly DNA to Dmel genome.

Notes:
  • Dmel genome size includes heterochromatin; only euchromatin was used for DNA matches.
  • This comparison uses a BLASTn cutoff of 1e-5 for genome assembly DNA to Dmel genome. Data are from ftp://eugenes.org/eugenes/genomes/
  • These data are based on most current assemblies as of February 2006; the comparative annotation freeze 1 set (CAF1).
