Crash when no fusions are present

[nrhorner]

Hi,

Using JAFFA v2.2.

I run JAFFAL and get a several fusion transcripts reported as expected.
In order to test what happens if no fusion transcripts are identified, I removed the previously found reads and rerun with the following command.

`bpipe run -n 4 -p jaffa_output="$JAFFAOUT/" -p refBase=chr20 -p genome=hg38_chr20 -p annotation=genCode22 -p fastqInputFormat="*.fastq" JAFFAL.groovy nofusion_genes_full_length_reads.fastq

Is there a way to prevent this happening?
