I was trying to generate a genome index using STAR index for mutant library 99,50 hours post fertilization (99H50) with the annotation form Lawson lab. The code I used is as follows.

module load STAR; STAR --runThreadN 10 --runMode genomeGenerate
--genomeDir /gpfs/ysm/scratch60/polimanti/ag2646/99H50_new_annotation/z10starindex75/
--genomeFastaFiles /gpfs/ysm/scratch60/polimanti/ag2646/Lawsonreference/genome.fa
--sjdbGTFfile /gpfs/ysm/scratch60/polimanti/ag2646/Lawsonreference/genes.gtf
--sjdbOverhang 75 the batch script used to submit the job for creation of such indices is  dsq --job-file z10starindex75.txt --job-name z10starindex75 -c 10 --mem=100G -t 10:00:00 --mail-type=ALL

I tried to run this code on my HPC cluster and it throws me an error as follows.

I googled and found out that such errors might originate from the allocation of memory and hence I ran from the space in the cluster where I have enough space. The memory usage for such job has been given by

Job ID: 47861791 Array Job ID: 47861791_0
Cluster: farnam User/Group: ag2646/nicoli State: FAILED (exit code 134)
Nodes: 1 Cores per node: 10 CPU Utilized: 00:36:34 CPU Efficiency: 45.14% of 01:21:00 core-walltime Job Wall-clock time: 00:08:06 Memory Utilized: 25.64 GB Memory Efficiency: 25.64% of 100.00 GB.

I browsed the internet and tried to find out solutions. (1) I tried to reduce the number of threads from 10 to 1 to reduce the computational memory issue. (2) I tried to use allocate specific memory limits by using flags like ---limitGenomeGenerateRAM 48000000000 (3) --genomeChrBinNbits 16 Still, the error is creeping in. First few lines of my GTF file is

Some of the lines of the genome fasta file is as follows


I have tried to provide as much detail as possible and any help will be helpful.

Edit: I redacted your email address from the post above.

Are you running this job outside a job scheduler? I don't see clear evidence of this being run via a job scheduler so perhaps cluster head node is killing your job.

Entering edit mode

I am running the job from a job scheduler. If the cluster head node is generating an error how to circumvent it?

Entering edit mode

Based on your original post it is hard to figure out how you are running this job. What scheduler are you using?

Entering edit mode

I am using a slurm based job scheduler. I am submitting a batch job using multiple job queues.dsq --job-file z10starindex75.txt --job-name z10starindex75 -c 10 --mem=100G -t 10:00:00 --mail-type=ALL --mail-user=xxx. If this answers your question.

Entering edit mode

While I am not familiar with this particular scripted way of submitting SLURM jobs but at least it must be running under the scheduler. So next obvious question is what is the size of /gpfs/ysm/scratch60/polimanti/ag2646/Lawsonreference/genome.fa? STAR may need way more than 100G of RAM if your fasta is > 10 GB in size (i.e. you have a reference with haplotypes etc).

Please use ADD COMMENT/ADD REPLY when responding to existing posts to keep threads logically organized. Also redact your email (I did that above) and any other system specific paths/names that may be sensitive information.
