Longest ORF

Description

Filtering a gff.table with ORF information to keep only the LORFs.

Usage

lorfs(gff.table)

Arguments

Details

For every stop-codon there are usually multiple possible start-codons in the same reading frame (nested ORFs). The LORF (Longest ORF) is defined as the longest of these nested ORFs, i.e. the ORF starting at the most upstream start-codon matching the stop-codon.

Value

A gff.table with a subset of the rows of the argument gff.table. After this filtering the Type variable in gff.table is changed to "LORF". If you want to retirve the LORF sequences, use gff2fasta.
