    Problem generating consensus files

    Hello all,

    I have been having trouble generating consensus files from sorted BAM files.

    I have tried both the mpileup command-

    samtools mpileup -uf ./genomes/NC_013316.fna 2245.sorted.bam | ../samtools-0.1.16/bcftools/bcftools view -cg - | ../samtools-0.1.16/bcftools/vcfutils.pl vcf2fq > 2245cns.fq

    and the depreciated pileup command -

    samtools pileup -cf ./genomes/NC_013316.fna 2245.sorted.bam | ../samtools-0.1.16/misc/samtools.pl pileup2fq -D150 > 2245pcns.fastq

    Both commands run correctly, however when I look at the fastq file it truncates at line 69857 and the rest of the files is filled with this character ( ~~~~) and random letters, as shown below -

    TCCATAAATTTAGTTATTCTGTAAAATTTATATATATTTTTGCTTTTCTGTTAATAACTT
    TGTGGAAAATATTAATTATTCTGTTCGGAGGTTTATatt
    +
    ?BBEEEEHNNNNNZZ`ccffiiloru~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

    Can anyone please explain what may be going on?
    I am very new to seq analysis and can't work it out!

    please ignore the last post!

    PLease ignore the last post, I have just realised that I have not converted my file to fasta, therefore I still have the quality called in the fastq file!

      samtools to convert Bam file to consensus sequence

      Hi, all:
      I tried to covert Bam file to consensus sequence as follow command:

      Samtools pileup -cf primatecom-sorted.bam samtools.pl pileup2fq -D100 > primate.fa

      error as follows:
      the Pileup command has been removed. please use mpileup instead.

      according to EmmBB, I tried mpileup. However, I didn't find samtools-0.1.18/bcftools/bcftools.

      Could you help me for this matter?

      Thank you very much,

      Runhua

        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,...
