GATK markduplicates out of memory

2

Hi,

I'm running into an issue with markduplicates. I am working with large fastq files and when running markduplicates there is an out of memory error. It doesn't look like there is enough storage on any of the nodes I have been trying to run markduplicates on. I have tried running it on a node with 1tb of memory. I'm not sure how much memory is available in --TMP_DIR /dev/shm/ because it varies. I was wondering if there was a way to fix this issue?
