  1. 1blastx + ve = blastx-positive, i.e. those transcripts or components that had received a positive hit to a known and putatively homologous protein sequence.
  2. 2Mean transcript size multiplied by number of spider blastx-positive components (genes) – with and without an additional 15% of components based upon Markov-ORF analysis (see text).
