Trimmomatic

[mmageroy]

Hi,
I am trying to run spruce WGBS through your pipeline.

Is it possible to run the pipeline without Trimmomatic? My reads are fairly have quality and the adaptors have been trimmed already. I am also having trouble with Trimmomatic not giving any output. See below.

Thanks!
Melissa

Hi @mmageroy

Thank you for using our pipeline.

Yes, it is possible to run if you already have Trimmomatic files. Please copy your trimmomatic output files into "Pipeline-RESULT-PATH/ trimmomatic-files/" then run the pipeline and select either "Run QC-Fastq-report" or "Run Bismark Mapper". The pipeline will read all the files from the "trimmomatic-files" directory and will start to run QC or Bismark-mapper.

Regarding the error message, I think the "trimmomatic-files" directory is empty, and when FASTQ is trying to read the files from that directory, you are getting this message. So, if you copy the files as I explained above, it should solve your problem.

Please let me know if you have any questions.
