  • how to find out mate reads?

    Hi,
    When I got the BAM file of alignments in the region of interest, how to retrieve the mate's data? I want to know how those mates are distributed throught the whole genome.

    Can you just visualize them on a viewer such as IGV?

      student-t, thanks for your reply.
      I use "samtools view originalfile.bam Chr4:100k-200k" to get a regional BAM file. In IGV, I can visualize the reads among my interested region. Because of Structure Viaration, the mates of those reads may not locate in the same region, and are not included in the BAM file.
      How can I get a file including data of those mates?

        Do you want to do this by hand/eye in a viewer? If so look at the full BAM file and the viewer should be able to show you the partner read (try right clicking etc). This is possible with Tablet via the tool tip, and you can right click to jump to the partner etc:


        Or, you can do this programatically by parsing the SAM/BAM file (e.g. in Python using pysam). There are specific columns used to report the mapping position of the partner read.

          Exploring the Dynamics of the Tumor Microenvironment
          by seqadmin




          The complexity of cancer is clearly demonstrated in the diverse ecosystem of the tumor microenvironment (TME). The TME is made up of numerous cell types and its development begins with the changes that happen during oncogenesis. “Genomic mutations, copy number changes, epigenetic alterations, and alternative gene expression occur to varying degrees within the affected tumor cells,” explained Andrea O’Hara, Ph.D., Strategic Technical Specialist at Azenta. “As...

          Exploring Human Diversity Through Large-Scale Omics
          by seqadmin


          In 2003, researchers from the Human Genome Project (HGP) announced the most comprehensive genome to date1. Although the genome wasn’t fully completed until nearly 20 years later2, numerous large-scale projects, such as the International HapMap Project and 1000 Genomes Project, continued the HGP's work, capturing extensive variation and genomic diversity within humans. Recently, newer initiatives have significantly increased in scale and expanded beyond genomics, offering a more detailed...
