So, I have to use a compute node. Clearly, the compute nodes capabilities() shows that png cannot be produced. Thank you for the command. It was helpful. >> >> I am not sure whether I have options.

If you inspect the HTML template found in the <r-path>/library/qrqc/extdata /fastq-report-template.html, you can see that the plot you are after is produced by qualPlot().
