RA stopped after preconstruction stage

Open vmurigneu opened this issue 6 years ago • 3 comments

Hi Robert,

I have installed RA following instructions without errors. But when I tried to run the following command: python /sw/ra/build/bin/ra -t 16 -x ont ont.fastq.gz > ra.fa

I get an empty assembly fasta file and the following message: [Ra::run] preconstruction overlap stage [M::mm_idx_gen::185.227*2.22] collected minimizers [Ra::exit] warning: unable to clean work directory!

Any idea?

Thanks in advance. Valentine

Hello Valentine, looking at the log I suspect that minimap crashed due to insufficient memory. How much RAM do you have? How large are your reads?

Best regards, Robert

Yes it is very likely to have insufficient memory. I have 31G and around 43G of compressed of human data. I am trying to run Ra on a larger memory node (120G).

Thanks.

Hmmm, not sure what minimap requirement is, but it seems to me that 120GB should be enough.
