    error when running samtools mpileup and bcftools

    Hi all

    I run the code below which is modified from [1]

    samtools mpileup -uf wg.fa ERR000589.srt.bam | /home/linp/linpDisk4/DataSeq/bcftools/bcftools call -mv -Oz

    But I encounter such a error:

    [mpileup] 1 samples in 1 input files
    <mpileup> Set max per-file depth to 8000
    [vcf.c:753 bcf_hdr_read] invalid BCF2 magic string: only BCFv2.2 is supported.
    Failed to open: -


    but I can successfully run samtools mpileup separately:
    samtools mpileup -f wg.fa ERR000589.srt.bam > ERR000589.bcf

    the ERR000589.bcf file looks as:
    chr10 60173 T 1 ^Z. H
    chr10 60174 T 1 . H
    chr10 60175 G 0
    chr10 60176 G 1 . /
    chr10 60177 G 1 . I
    chr10 60178 T 1 . .
    chr10 60179 T 1 . 8
    chr10 60180 G 1 . G
    chr10 60181 G 1 . I

    Could anyone please give me some tips about what happened?

    Try:
    Code:
     samtools mpileup -ugf wg.fa ERR000589.srt.bam | /home/linp/linpDisk4/DataSeq/bcftools/bcftools call -mv -Oz

      Thank you dpryan!

      But the problem still exists:

      linp@wuserver:~/linpDisk4/DataSeq$ samtools mpileup -ugf wg.fa ERR000589.srt.bam | /home/linp/linpDisk4/DataSeq/bcftools/bcftools call -mv -Oz
      [mpileup] 1 samples in 1 input files
      <mpileup> Set max per-file depth to 8000
      [vcf.c:753 bcf_hdr_read] invalid BCF2 magic string: only BCFv2.2 is supported.

        My only guess is that you have different versions of samtools and bcftools (make sure you're using the tagged 1.0 version of both if you got this from github). If that's not the case and no one else is able to give you an answer here then you should post this to the samtools-help email list.

          Thank you dpryan!

          the versions are:

          Program: bcftools (Tools for variant calling and manipulating VCFs and BCFs)
          Version: 1.0-15-gc15888a (using htslib 1.0-2-g1903fd4)
          Program: samtools (Tools for alignments in the SAM format)
          Version: 0.1.19-44428cd


          Do you think they are in-compatible ?

            Ah, yeah, you need to either use the version of bcftools that came with samtools 0.1.19 or use the newer version of samtools available here.

              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,...

              Multiomic Liquid Biopsy: What DNA/RNA Panels Reveal That DNA Alone Can’t
              by SEQadmin2



              Tumors contain complex mixtures of cell populations that evolve in response to treatment and host-specific factors. Tissue biopsies provide only static snapshots of a tumor’s state. But what if we could follow that evolution over time using a minimally invasive technique?

              Liquid biopsies can detect tumor-derived material circulating in the bloodstream, providing a way to study treatment response, detect emerging resistance, and discover new biomarkers. Circulating
