I am trying to align R1 paired, and R2 paired fastq files(15 GB) to a reference genome(1.35 GB) through bwa-mem but even after spending 6 hours, I did not get any result and it’s just showing yellow colour.
How long should it take?
This sounds like a job that is still executing:
Try to let it finish. If you delete and rerun, that places the new job back at the end of the queue, extending wait time. I added a tag to your question that points to prior Q&A about how jobs process using the shared resources at the public servers.
