  • Transfer a whole genome with .bam format

    Dear all,

    Do you have experience to transfer a whole genome of short-reads with ~35X sequenced by Illumina GA to .bam format using samtools? I feel very strange when I got more than 500G data. I addition, how can you extract chromosomes one by one and sort as well as index them? Thank you very much!

    Never had a whole genome with that coverage :-( Sorted BAM may be slightly smaller.
    To extract a single chrom (or a single region) index it

    Code:
    samtools index file.bam
    and then extract your region

    Code:
    samtools view file.bam chrom[:start-end]

      Thanks for your answer, dawe.

      But why did you say "Never had a whole genome with that coverage "? Most of the sequenced individuals such as YH (PMID:18987735) and AK1 (PMID:19587683) were higher than that coverage (>35X).

        :-) I usually deal with ChIP-seq or exome analysis, never had a "first hand" high coverage of human genome.

          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...
