Segmentation Fault #2072

Open AhmedSAHassan opened 4 months ago

AhmedSAHassan commented 4 months ago

Hi, I am pretty new to using STAR and I am receiving a segmentation fault error message when trying to execute this command STAR --runMode genomeGenerate --genomeDir geneIndex/ --genomeFastaFiles Homo_sapiens.GRCh38.dna_sm.primary_assembly.fa --sjdbGTFfile Homo_sapiens.GRCh38.111.gtf --runThreadN 4

I am working on Ubuntu subsystem on a Windows machine.

how can I fix this issue? Thanks in advance

I guess you just ran out of memory. How much memory do you have?

AhmedSAHassan commented 4 months ago

Thanks for your reply. Ok, that's probably the problem. I have 16GB of RAM

kuowenhsi commented 4 months ago

For a human genome, 16GB sounds a little limited. I'd suggest try it again on a 32GB up and a real Linux-based system. Hope it is helpful.
