transdecoder

find coding regions within RNA transcript sequences

Description

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.
