As part of annotating the transcriptome assembly from the MEGAN6 C.bairdi taxonomic-specific reads, I need to run DIAMOND BLASTx to use with Trinotate.
Ran DIAMOND BLASTx against the UniProt/SwissProt database (downloaded today) on Mox.

Well, this ran in a riduculous 6 seconds!
Seriously, 14,000 query sequences were aligned in 6 seconds!

BLASTx output - BLAST format 6 (tab):
Will proceed with Trinotate.
