As part of annotating cbai_transcriptome_v3.0.fasta from 20200518, I need to run DIAMOND BLASTx to use with Trinotate.

Ran DIAMOND BLASTx against the UniProt/SwissProt database (downloaded 20200123) on Mox.

### BLASTx of Trinity de novo assembly of all pooled C.bairdi RNAseq data:
### cbai_transcriptome_v3.0.fasta (orginal name, used below, is 20200518.C_bairdi.Trinity.fasta)
### Includes "descriptor_1" short-hand of: 2020-UW, 2019, 2018.

RESULTS

As usual, runtime was ridiculously fast: 23 seconds
