## Description

The exoniphy program identifies evolutionarily conserved protein-coding exons in a multiple alignment using a phylogenetic hidden Markov model (phylo-HMM), a statistical model that simultaneously describes exon structure and exon evolution. This track shows exoniphy predictions for the human Feb. 2009 (GRCh37), mouse Jul. 2007 (mm9), rat Nov. 2004 (rn4), and dog May 2005 (canFam2) genomes, as aligned by the multiz program. For this track, only alignments on the "syntenic net" between human and each other species were considered.

## Methods

For a description of exoniphy, see Siepel et al. (2004). Multiz is described in Blanchette et al. (2004). The alignment chaining methods behind the "syntenic net" are described in Kent et al. (2003).

Thanks to Melissa Hubisz of the Siepel lab at Cornell University for producing these predictions.
