Genscan Genes (genscan) Track Description


This track shows predictions from the Genscan program written by Chris Burge. The predictions are based on transcriptional, translational and donor/acceptor splicing signals as well as the length and compositional distributions of exons, introns and intergenic regions.

For more information on the different gene tracks, see our Genes FAQ.

Display Conventions and Configuration

This track follows the display conventions for gene prediction tracks.

The track description page offers the following filter and configuration options:

  • Color track by codons: Select the genomic codons option to color and label each codon in a zoomed-in display to facilitate validation and comparison of gene predictions. Go to the Coloring Gene Predictions and Annotations by Codon page for more information about this feature.


For a description of the Genscan program and the model that underlies it, refer to Burge and Karlin (1997) in the References section below. The splice site models used are described in more detail in Burge (1998) below.


Thanks to Chris Burge for providing the Genscan program.
