Description 
This track shows Evolutionary Conserved Regions computed by the 
Exofish program at Genoscope.
Each singleton block corresponds to an "ecore"; two blocks connected by a thin line 
correspond to an "ecotig", a set of colinear ecores in a syntenic region.  
 Methods 
Genome-wide sequence comparisons were done at the protein-coding level between the genome sequences
of the fruitfly, Drosophila melanogaster and the mosquito, Anopheles gambiae to
detect evolutionarily conserved regions (ECORES).  See 
Assessing the Drosophila melanogaster and Anopheles gambiae genome annotations using 
genome-wide sequence comparisons.  Jaillon  et al. Genome Res. 2003 Jul;13(7):1595-9.  
The sequence versions used in the comparison were 
Ensembl Drosophila v.16.3a.1 (Jan. 2003, the same as BDGP Release 3.1 
used by the UCSC Genome Browser) and 
Ensembl Anopheles v.16.2.1 .
