To continue annotation of our C.bairdi v2.1 & v3.1 transcriptome assemblies, I needed to run TransDecoder before performing the more thorough annotation with Trinotate.

Info for each transcriptome version (library composition, assembly dates, BUSCO, etc) can be found in this table:

cbai_transcriptome_comp

This was run on Mox.
