Default bbtools: how to properly set up rqcfilter

Dear all,
I've recently obtained some PE RNA-seq data from JGI. They have been cleaned using the rqcfilter tool (v. 37.17). Since I would like to uniform the cleaning method extending it to other previously obtained Illumina data, I would like to set up my server to be able to run rqcfilter. I'm aware that this script has been hardcoded to run on on Genepool...but it worth to give a try.

Here follow the steps run by the RQCfilter, as deduced by the reproduce outputs, on my PE data:

> pigz=t unpigz=t zl=4 reorder in1=OMISSIS.fastq.gz out1=TEMP_CLUMP_8352bfa6997ae09cc4039681816c_OMISSIS.anqrpht.fastq.gz passes=1

I have highlighted in bold the files that, at a first glance, are missing. Where can I find them? while it's pretty clear what could be the content of adapters2.fa and pJET1.2.fasta, what's the content of the short.fa file?

about the contaminant removal, should I retrieve also human and cat/dog/mouse/microbial references or the script does it itself?

Thanks for any hints you may provide!
