Whole genome alignment 
Tutorial
Two types of pairwise genome alignment are available in VectorBase, based on LastZ [1] and translated BLAT (tBLAT) [2]. LastZ is typically used for closely related species, and tBLAT for more distant species. The method of alignment affects the coverage of the genomes, with tBLAT expected to mostly find homologies in coding regions.
The raw results from LastZ or tBLAT are alignment blocks, which are 'chained' according to their location in both genomes, then 'netted' to choose the best sub-chain in each region for the reference species [3].
Coverage statistics are available for all pairwise alignments (e.g. Anopheles gambiae and Anopheles coluzzii).

Pairwise alignments are viewable in the genome browser, and are also available for download in bulk.
