GENSCAN
In bioinformatics GENSCAN is a program to identify complete gene structures in genomic DNA. It is a G HMM-based program that can be used to predict the location of genes and their exon- intron boundaries in genomic sequences from a variety of organisms. The GENSCAN Web server can be found at MIT.
GENSCAN was developed by Christopher Burge in the research group of Samuel Karlin Department of Mathematics, Stanford University.
