Hi Xingbo,
Kinda late reply, but hope it might help if necessary.
I struggled getting Juicer running on SLURM as well. I usually manage my other software using Conda, however, it seems like you don't need it for Juicer.
Our HPC has modules system and the necessary modules (bwa, java, etc.) were already installed. So I just changed the path to these modules in the script and partition names according to our cluster.
