Running IGV from OOD interactive desktop

IGV is also available from an interactive desktop job, giving the full desktop experience. Because the IGV interface is programmed in Java, we must tell IGV how much memory is available in our job context. If we don't then the default value of 2 GB is used, likely insufficient. Please see Java Xmx for more information and a more robust method of calculation. The instructions below assume an interactive desktop job has been created and prepared and that the terminal is open in that interactive desktop. This may be done using the Open OnDemand web portal. 

module load IGV/<version>  # replace <version> with one available in the list from `module avail IGV`
avail_mem=$(($SLURM_MEM_PER_CPU * $SLURM_JOB_CPUS_PER_NODE))
heap_mem=$((avail_mem - 512)) # leave 512 for the JVM itself, rest for heap
igv.sh -Xmx${heap_mem}m
