I previously created a C.bairdi de novo transcriptome assembly with Trinity from the MEGAN6 taxonomic-specific reads for Arthropoda on 20200122 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 "%").
