### 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 rat, Rattus norvegicus, and Tetraodon, Tetraodon nigroviridis, to detect evolutionarily conserved regions (ECORES). The sequence versions used in the comparison were Rat (June 2003) and Tetraodon (March 2004).
