Exception in thread TaskFileWriter-Thread:

Dear author,

Thanks for developing this software. I re-aligned my bam files with the provided reference genome, then ran Accucopy docker image with Singularity following the instructions, but I always get the following errors:

I might have missed something. Any suggestions? Thanks.

This looks quite strange. pyflow is the software that connects all components together. Do you know which step it was running when this error occurred? If you re-run the same commandline, you need to clean up the whole pyflow folder. You can send the whole status output folder (barring the actual data output) to ***@***.*** Sorry for the delay in replying. Too many emails, just noticed this on github. :)

Hello Yu,

Thanks for the work put into this tool, I was very happy to come across a somatic CNV tool that works well with low coverage samples.
I have recently started to use Accucopy and while my tests were successful (i.e. complete output files and successful log conclusion), however after implementing the tool into a pipeline. I also received the same error as @zhujack

I've done my best to trace the bug and the issue seems to be with PyFlow not creating the {OUTPUT_DIR}/pyflow.data/state directory or any of the files needed in this directory i.e. pyflow_tasks_info.txt as referenced in the error message.
There are other errors related to files in this directory not existing.
Furthermore, the error is confusing as the same block of code in the pyflow.py script that is used to create the state directory also creates the {OUTPUT_DIR}/pyflow.data/logs directory which does exist and contains the correct files.

        ensureDir(stateDir)

Additionally, the issue does not seem to present in Strekla2's output which I found uses an alternative pyflow installation.
Perhaps we could point Accucopy to use this installation of pyflow?

I can expand on the error with more log and output files, just let me which you might need.
I will also follow this issue with an email to you as well.

Best,
Patrick

Hello,
Can you pack and upload the dir {OUTPUT_DIR}/pyflow.data or send it to my email(xinpingfan@gmail.com)?

Which container you have used, Docker or Singularity?

How do you implement Accucopy into a pipeline, wrap it in a Makefile or shell script and submit to SGE?

Best,
Xinping

[pblaney]

Hi @fanxinping,

Thank you for getting back to me on this. I have sent you the zipped file of the {OUTPUT_DIR}/pyflow.data.
I am using a Singularity container. It was created by converting the docker image from polyactis/accucopy:latest to a Singularity SIF file.
I have implemented Accucopy into pipeline that executes Accucopy with a shell script and uses SLURM as a job scheduler.

Hope this helps shed light,
Patrick

Hi @pblaney

I have checked the zipped file of the {OUTPUT_DIR}/pyflow.data. The file pyflow.data/logs/pyflow_tasks_stderr_log.txt doesn't contain any error message and shows that Accucopy run successfully. The file pyflow.data/logs/pyflow_tasks_stdout_log.txt contains the complete output of Accucopy, which indicates Accucopy has output the results.

Maybe you have sent the wrong file to me. Can you send the log file which contains the follow message?

@fanxinping,

I just sent you the log file that captured those errors.
As you note, the Accucopy output is intact and nothing appears to be wrong with its execution. However, this error causes the job to reflect as failed and thus does not propagate the output to the next process.
But as you can see in that zipped directory that there is no state directory which is the cause of the errors.

@pblaney

It's very strange. I have tested Accucopy in my SLURM env, and it worked well.
The shell script is test.sh:

#!/bin/sh

singularity exec --bind /y accucopy_latest.sif /usr/local/Accucopy/main.py -c configure_hg38 -t tumor.bam -n normal.bam -o result --nCores 15

and use this command to submit:

sbatch --cpus-per-task 15 -o test.output test.sh

I think you should check SLURM env or the subsequent process in the shell script. Maybe some operation delete state directory accidentally.

You can share your shell script and submit command if possible.
