  • Info about rf vs fr with samtools or other?

    I am working with Illumina GAII derived mate pair data. I am attempting to identify two things in the sequences so that I can get rid of spurious data:

    1. Are the reads rf or fr. I know picard must have the ability to identify this info from a sam as it provides such output when running the ColleceInsertSize... However, the output format is not what I need. Is there another tool that can provide rf/fr data for reads or is there a way to extract it from the sam?

    2. Chimeric sequences. Not even sure where to begin here.

    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...
