Decided to annotate the two C.bairdi transcriptomes , cbai_transcriptome_v2.1 and cbai_transcriptome_v3.1, generated on 20200605 using DIAMOND BLASTx on Mox.

## Script for running BLASTx (using DIAMOND) to annotate
## C.bairdi transcriptomes v2.1 and v3.1 against SwissProt database.
## Output will be in standard BLAST output format 6.

RESULTS

Super fast - 40 seconds to process both transcriptomes:

cbai v2.1 and v3.1 diamond blastx runtime

Output folder:

20200608_cbai_diamond_blastx_v2.1_v3.1

BLASTx output files (BLAST output format 6 text):

Will put link to each annotation on the Genomic Resources wiki.
