  • Bam file to Consensus Fasta/fastq in python

    Hello!

    Summary:
    I want to get the same result as I get from this command, but in python (BioPython/Pysam):
    Code:
    samtools mpileup -uf ref.fa aln.bam | bcftools view -cg - | vcfutils.pl vcf2fq > cns.fq
    Full story:
    I need to extract the consensus fasta from an aligned bam file, currently I'm doing it with samtools, but I'll be more than happy if I can implement it in python without 3rd party tools. That's important because this step is an intermediate step, so I need this fasta sequence to play with it.

    Thanks everyone for your help.

    Best,

    Daniel.

    Can't you call these tools within your Python script? As long as machine you are running have the tools installed, it should be fine.

    Editing:
    Sorry, when read you message a second time, I realized that you said you do not want to use third party tools.
