  predicts coding exons and conserved noncoding regions in a pair of homologous 
  DNA sequences, incorporating both statistical sequence properties and degree of 
  conservation in making the predictions.  This particular annotation uses the Nov. 2002 (hg13) assembly of the human genome. The model is symmetric and the same gene structure (with possibly different exon lengths) is predicted in both sequences.

  <P>
  The symmetry of the model gives it a higher degree of accuracy for regions where the true underlying gene structures contain the same number of coding exons, in cases where this is not true, or when one of the sequences is of lower quality and contains in-frame stop codons, the resulting predictions tend to have lower accuracy.
