Will wtpoa-cns automatically exit after the run is complete?

Abnormal. What's about the log information? Could you copy the text here.

No longer change and don't quit
But I did get this file ‘’BAC_nanopore.final.fa’’

Thanks Jianshun!

Please try new commit 31cf61b

Hi,

Jumping on this closed issue here because I think that I'm seeing the same behavior.

wtpoa-cns appears to hang and not finish. The end of the log file lists that it has gone through all of the contigs and edges, but the program does not exit.

I'm working off of the most recent commit

git show --oneline -s
5009cff fixed a bug in option -K

My command was:

wtpoa-cns -t 20 -i [filename].ctg.lay.gz -o [filename].ctg.lay.fa

---

For reference, my wtdbg2 command was:

wtdbg2 -t 20 -i concatenated_reads.fasta \
   -fo output_wtdbg2 \
   -p 0 -k 15 -AS 2 -s 0.05 -L 8000 \
   -g 3.1g \
   --edge-min 2 --rescue-low-cov-edges --aln-noskip \
   --ttr-cutoff-depth 20 \
   -K 1000.0

Here is the tail of the wtdbg2 output:

Dear zrlewis,

I cannot locate the bug from reading the code, for I haven't find a test data reproduce this problem.

If anyone find a small test data, I will continue to work on it.

Best,
Jue

[zrlewis]

@ruanjue Thanks for looking into it. I'm trying a couple new assemblies from scratch using the most recent commit and will let you know if I still encounter the problem.

[zrlewis]

@ruanjue wtpoa-cns finished this time after running both wtdbg2 and consensus from the most recent commit. I had previously been running a slightly older wtdbg2 version. It was labeled Version: 2.2 (20181111), but I don't have the commit. That could have been the problem.

[ruanjue]

I believe there is still similar problem in wtpoa-cns, but have no idea where to find it. Let's talk about it when it re-occuring.

Hi,
I am using latest copy of wtdbg2 from github. I also see a similar issue. wtpoa-cns reaches very end and then don't exit. i dont know whether this issue is related to the parameters I used in wtdbg2 run. I never issues before when I ran wtdbg2 with default settings.

[ruanjue]

It looked like some contig took very long time or endless. Try to split the input fle into multiple ones, and run wtpoa-cns seperately.

[shri1984]

Thanks. You are right, there is one contig look endless.
I managed to split the ctg.lay file into multiple files and manage to finish them independently. However, when I counted the number of contigs in ctg.lay and concatenated (from independent files) .raw.fa. I observed a difference of 1 contig, and I isolated that contig which is not showing up in the final raw. fa and run it wtpoa-cns. It does not look like finishing any time soon. It is running for 2 hours for that one contig. any input?

[ruanjue]

If the contig file is small, please send it to me ruanjue.big(AT)qq.com.
