  • bbwrap.sh, is output OK?

    Hi all,

    I have a library sequenced two times in paierd-end mode.

    I have used bbwrap.sh

    ~/bin/bbmap/bbwrap.sh -in1=hds1r1_09clean.fastq.gz,hds1r1_26clean.fastq.gz -in2=hds1r2_09clean.fastq.gz,hds1r2_26clean.fastq.gz path=/media/mj/c8e2ccd2-6313-4092-be34-46144891720f/agp_v5 unpigz=t pigz=t threads=24 -Xmx100g outm=s68_to_b73v5.bam showprogress=250000 statsfile=stats_s68_to_b73v5 covstats=covstats_s68_to_b73v5

    If I understand correctly it is possible to provide paired files in -in and -in2

    The procedure proceeded ok, like bbmap.sh, after processing the first pair it printed info, which I expected:

    I'm surprised to see "No output file." in the messages above. Also the entire output ended with "total time" and no statistics as for the first read-pair.

    So in the end I wonder if my resulting file is ok (I used outm to get only mapped reads). I.e. does it contain mapped reads from all four files?

    I don't want to test if, for example merged file from separate runs of bbmap for both pairs would give the same number of mapped reads. It would take too much time.
    bbwrap seems ok, but from my point of view it is not enough documented.

    You can't use `-in1=` those options are simply `in1=` and `in2=` etc. You should also use `out=` not `outm=` if you are writing an alignment file.
    Code:
    bbwrap.sh in1=read1.fq,singleton.fq in2=read2.fq,null out=mapped.sam append

      Thanks,

      so can I write:

      bbwrap.sh in1=hds1r1_09clean.fastq.gz,hds1r1_26clean.fastq.gz in2=hds1r2_09clean.fastq.gz,hds1r2_26clean.fastq.gz ... out=s68_to_b73v5.bam

      ?

      Why I have to use "out" but not "outm"? I want to retain only mapped reads, to keep my file as small as possible.

      It is also interesting, why bbwrap haven't alert that options such as "-in1" are invalid. Some output file has been written but I don't know if it is valid. At least bamqc accepted that file. Nevertheless I'd rather want properly generated file, even if it means that I have to wait for it ten days.

        That would be fine. Looks like you can use `outm=` if you need just mapped reads. I have normally used `out=` with `mappedonly=t` but those two look to be equivalent.

        It should not take 10 days to complete an analysis unless you have a huge dataset.

          Ok, thanks. I have huge dataset so I will have to wait for results.

            So my mapping crashed. Here is my command:
            ~/bin/bbmap/bbwrap.sh in1=hds1r1_09clean.fastq.gz,hds1r1_26clean.fastq.gz in2=hds1r2_09clean.fastq.gz,hds1r2_26clean.fastq.gz path=/media/mj/c8e2ccd2-6313-4092-be34-46144891720f/agp_v5 unpigz=t pigz=t threads=24 -Xmx100g outm=s68_to_b73v5.bam append showprogress=250000 statsfile=stats_s68_to_b73v5 covstats=covstats_s68_to_b73v5 bs=bs.sh

            Here is the error message

            **************************************************************************
            I don't have to necesarily use bbwrap, I just wanted to make mapping in elegant way.
            So just to make sure, could I map first pair and second pair of read separately with bbmap and then merge the results (bam files)? I don't have time for more tries, I have been waiting five days for this error.

              Ok, so I've found samtools merge.

                You need to map paired end files together before merging the resulting alignment files using samtools merge.

                  by seqadmin




                  The complexity of cancer is clearly demonstrated in the diverse ecosystem of the tumor microenvironment (TME). The TME is made up of numerous cell types and its development begins with the changes that happen during oncogenesis. “Genomic mutations, copy number changes, epigenetic alterations, and alternative gene expression occur to varying degrees within the affected tumor cells,” explained Andrea O’Hara, Ph.D., Strategic Technical Specialist at Azenta. “As...

                  In 2003, researchers from the Human Genome Project (HGP) announced the most comprehensive genome to date1. Although the genome wasn’t fully completed until nearly 20 years later2, numerous large-scale projects, such as the International HapMap Project and 1000 Genomes Project, continued the HGP's work, capturing extensive variation and genomic diversity within humans. Recently, newer initiatives have significantly increased in scale and expanded beyond genomics, offering a more detailed...
