GrailEXP is a software package that predicts exons, genes,
promoters, polyas, CpG islands, EST similarities, and repetitive
elements within DNA sequence. GrailEXP was originally developed the
Biosciences Division
at Oak Ridge National Laboratory
to annotate the entire known portion of the human genome (including
both finished and draft data).
Version 6.2 was created by John Eblen, Dr. George Maalouf, Ray Surface, and Dr. Ed Uberbacher.
EXP6, formerly proprietary software of Genomix Corporation, Oak Ridge, TN, is
a highly accurate, robust gene finder. EXP6 combines the strengths of various
techniques for gene finding into one package to try and be as accurate as
possible. It first uses statistical techniques to pinpoint possible locations
of exons. Then it brings in empirical evidence from nucleotide and protein
databases to create possible "pieces" of genes. Finally, an intelligent
algorithm constructs the genes from these pieces. At Genomix, we spent a
great deal of effort over a span of nearly two years improving EXP6,
especially the final algorithm to construct the genes.
EXP6 is now free software under the GPL license.
The software is no longer supported by anyone from the Oak Ridge National Laboratory
but is still available for download using the download link.
