  • samtools view -l/-r options

    Hi everyone!
    Is it possible to retrieve mapping results of several specific reads from bam or sam files by referring to the read names?

    I tested the following options and couldn't get it working:

    -l STR only output reads in library STR [null]
    -r STR only output reads in read group STR [null]
    -R FILE list of read groups to be outputted [null]

    I have a txt file that includes names of several candidate reads, and I would like to extract the mapping info of the reads from a bam/sam file.
    Could some one please provide an example script on how to do that?

    Thank you!

    Cheers.

    Check out the fgrep command with the -f parameter.

    samtools view file.bam | fgrep -f candidates.txt

    Play around with a small examples to figure out how to use fgrep.

      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...

      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...
