I previously created a C.bairdi de novo transcriptome assembly v4.0 with Trinity from all our C.bairdi RNAseq reads which had BLASTx matches to the C.opilio genome and decided to assess its “completeness” using BUSCO and the metazoa_odb9 database.

BUSCO was run with the --mode transcriptome option on Mox.

## Set paths to various programs
### The use of the % symbol sets the delimiter sed uses for arguments.
### Normally, the delimiter that most examples use is a slash "/".
### But, we need to expand the variables into a full path with slashes, which screws up sed.
### Thus, the use of % symbol instead (it could be any character that is NOT present in the expanded variable; doesn't have to be "%").

RESULTS

As usual, runtime was very short, <2mins:
