The July 2004 Drosophila ananassae genome assembly was produced by The Institute for Genomic Research (TIGR) and can be downloaded here. To see a list of the assembly's largest 1000 scaffolds ranked by size, click here.

### Sample position queries

A genome position can be specified by a scaffold coordinate range, the accession number of an mRNA or RefSeq entry, a gene name, or keywords from the GenBank description of an mRNA. The following list shows examples of valid position queries for the D. ananassae genome. Note that some position queries (e.g. "huntington") may return matches to the mRNA records of other species. In these cases, the mRNAs are mapped to their homologs in D. ananassae. See the User's Guide for more information.
