    Error in samtools merge; different target sequence name

    I am now making a script with bowtie and samtools, and
    troubled in merging bam files from bowtie.
    1) bowtie with every chromosome ewbt; output is sam file
    2) sam to bam (every chromosome sam file)
    3)* merge all bams
    4) bam sort
    5) bam index

    #!/bin/sh
    date=`date +"%Y%m%d_%H%M"`
    samtools merge ${date}.bam ${date}_bam_chr1.bam, ${date}_bam_chr2.bam,... ,${date}_bam_chrY.bam

    error massage was
    [bam_merge_core] different target sequence name : 'chr1' != 'chr2' in file 20110115_0050_bam_chr2.bam

    In this case, date was 20110115_0050.
    What was wrong??

    Hi,

    I had the same problem.

    Check that chromosomes headers are in the same order in the headers of all the bam files.

    Cheers

      The part about this topic feels surprisingly grounded, and the details on the page is the bit that made me slow down. I’d keep <a href="https://kinpict.com/">ai family photo generator</a> bookmarked for later.

      16S/ITS Profiling vs. Shotgun Metagenomics: What Changes in Your Workflow?
      by SEQadmin2





      NGS has revolutionized clinical microbiology by offering new ways to identify and surveil pathogens without prior knowledge of the target. One popular approach is 16S rRNA and ITS amplicon sequencing, which targets specific microbial markers. But studies are increasingly incorporating shotgun metagenomics, a technique that sequences all DNA from a sample without targeting specific microbial markers. This approach allows more detailed taxonomic classification,...
