find coding regions within RNA transcript sequences
TransDecoder identifies candidate coding regions within transcript sequences, such as those generated by de novo RNA-Seq transcript assembly using Trinity, or constructed based on RNA-Seq alignments to the genome using Tophat and Cufflinks.
TransDecoder identifies likely coding sequences based on the following criteria:
* a minimum length open reading frame (ORF) is found in a transcript sequence * a log-likelihood score similar to what is computed by the GeneID software is > 0. * the above coding score is greatest when the ORF is scored in the 1st reading frame as compared to scores in the other 5 reading frames. * if a candidate ORF is found fully encapsulated by the coordinates of another candidate ORF, the longer one is reported. However, a single transcript can report multiple ORFs (allowing for operons, chimeras, etc). * optional the putative peptide has a match to a Pfam domain above the noise cutoff score.
