This is the error that I am getting:

I think the main problem is the "mpileup: unrecognized option --region", which seems to be blank. In the beginning of the block, it says creating pileup and then it immediately removes the file, probably to create the pipeline file.

I cannot change the code for Lyve-SET pipelining or create shell scripts for the pipeline because I am only configuring my server for use with the genome sequencing pipeline. Would this be a problem with the data set or some tool that I need to install? Any insight would be appreciated.

  • $\begingroup$ What version of samtools mpileup to you have installed? What version of varscan are you using? Did you install the two tools separately or did varscan come with samtools? I have version 1.3.1 and there is a --region option for mpileup. $\endgroup$

  • $\begingroup$ Have you tried running samtools mpileup -f lambda/reference/reference.fasta -Q 0 -B --region NC_001416.1 /home/user/lyve-SET-1.1.4f/lambda/bam/NC001416.fasta.wgsim.fastq.gz-reference.sorted.bam directly to see if the command works outside the context of varscan? $\endgroup$

  • $\begingroup$ I installed samtools version 0.1.19 using yum install. Varscan was installed separately through make install from Lyve-SET. I did not try to run samtools mpileup separately because all the commands are implemented through Lyve-SET, which is how it will be run by the user. I will try reinstalling varscan and running the samtools mpileup command separately. Thank you for the help. $\endgroup$

  • $\begingroup$ I would suggest installing a more recent version of samtools. That version is from 2013 is likely is not compatible with the version of varscan you installed $\endgroup$

  • $\begingroup$ Yup. I noticed that yum patches but does not update the packages so I am manually installing the newest versions of all the tools specified in Lyve-SET. Thank you for bringing this to my attention. Hopefully it works after I reinstall. $\endgroup$

The samtools v0.1.19 manual confirms that there is no --region option. In that version there is only the -r argument to pass in the targeted region. If you update to a newer version of samtools this should execute correctly

  • $\begingroup$ It worked after I reinstalled all the tools. The main problem was the mpileup error where --region was not an option. Cannot trust some of these yum packages as they are much older versions. Thank you so much for helping me with this issue. $\endgroup$
