  • Samtools mpileup_Paired Tumoral / Germline_keep only somatic mutations

    I performed a genomic capture (Agilent technologie, SureSelect Target Enrichment System for Illumina Paired-end Sequencing) with paired tumoral and constitutional DNAs.
    I created a .bam file for each both. I used bwa for alignment and samtools to create my bam file.
    Now, I would like to call somatic mutations from these pair of samples (Tumoral vs Germline) with samtools (example of commands : samtools mpileup -DSuf ref.fa aln.bam | bcftools view -bvcgT pair - > var.bcf ). The goal is to eliminate all the commons mutations present in the two samples in order to keep only the somatic mutations.
    Anybody can help me to understand how to realize this step?
    What is the command for samtools ?
    Thank you very much for your help

    did you check VarScan? It declares somatic state for each SNP/indel and provides some nice statistics by inputting the pileup files of the tumor/normal samples.

      Sam64, it sounds like VarScan might be better suited to your needs.

        Essential Discoveries and Tools in Epitranscriptomics
        by seqadmin


        The field of epigenetics has traditionally concentrated more on DNA and how changes like methylation and phosphorylation of histones impact gene expression and regulation. However, our increased understanding of RNA modifications and their importance in cellular processes has led to a rise in epitranscriptomics research. “Epitranscriptomics brings together the concepts of epigenetics and gene expression,” explained Adrien Leger, PhD, Principal Research Scientist on Modified Bases...

        Current Approaches to Protein Sequencing
        by seqadmin


        Proteins are often described as the workhorses of the cell, and identifying their sequences is key to understanding their role in biological processes and disease. Currently, the most common technique used to determine protein sequences is mass spectrometry. While still a valuable tool, mass spectrometry faces several limitations and requires a highly experienced scientist familiar with the equipment to operate it. Additionally, other proteomic methods, like affinity assays, are constrained...
