Merge

  1. Map on JGI ver 7.1 genome with GMAP (default setting).
  2. Sort all transcripts based on CDS length identified by GMAP (from longest to shortest). For transcripts with identical CDS length, sort them based on exon length also identified by GMAP (from shortest to longest; when I did this second sorting in opposite way, there were so many fused genes produced so I decide to sacrifice long UTRs instead).
  3. Choose longest transcripts per give genome scaffold region and direction of transcription.

Translation

  1. Translate non-redundant transcripts into all possible 6 frames, with standard codon usage table.
  2. Search it against Reference species proteome (human, mouse, zebrafish, chicken, X. tropicalis; EnsEMBL ver. 72)
  3. Determine the translation frame
