Hello, i just installed Wengan and im having this problem. Im running Wengan in a cluster in a single node!

Command:
perl /opt/BIO/wengan-0.2/wengan.pl -x ontraw -a A -s R-subs-0.1-1P.fastq.gz,R-subs-0.1-2P.fastq.gz -l PaeAG1-long.fastq.gz -p ensamblaje-wengan -t 20 -g 7000000

Problem:
perl /opt/BIO/wengan-0.2/wengan.pl -x ontraw -a M -s R-subs-0.1-1P.fastq.gz,R-subs-0.1-2P.fastq.gz -l PaeAG1-long.fastq.gz -p ensamblaje-wengan -g 7000000
/opt/BIO/wengan-0.2/bin/liger --mlp 10000 -t 1 -c ensamblaje-wengan.MBC7.msplit.fa -l longreads.ensamblaje-wengan1.fa -d ensamblaje-wengan.MBC7.msplit.cov.txt -p ensamblaje-wengan -s ensamblaje-wengan.sams.txt 2>ensamblaje-wengan.liger.err >ensamblaje-wengan.liger.log

Hi Jose,

Can you share additional log files or error, from your message I just can infer that the assembly failed at the last step.
thanks in advance,
Alex

Wengan crash because there are really few contigs and therefore links, it seem that there is an issue with the short-read data. I suggest to assess the quality of the short-read data with:

https://github.com/digenoma-lab/k-count-nf

That will give you an estimate of the genome size and will be helpful to determine the quality of the short-read data. that then you can post here to discuss.

Best,
Alex
