Welcome to GPF

The Genomic Peptide Finder is a tool that matches de novo predicted amino acid sequences to the genomic DNA sequence of an organism. The matching procedure is error-tolerant to accomodate possible de novo sequencing errors due to individual missing fragment ions in the MS/MS scan. In addition, spliced peptides can be deduced from genomic DNA.

GPF has been devised by Jens Allmer and Michael Hippler in 2003, with subsequent design changes and re-implementation by Michael Specht starting in 2007.
