    A tool to assemble diploid gene sequences?

    Suppose I have a bam file that contains mapping of reads to the human reference. Then for a particular gene, I want to reconstruct its two haplotypes. Is there a tool to assemble reads mapped to the said gene region into two haplotypes? Thanks!

    You can extract reads from a given region from your sam/bam file. about assembling it ... u should be assemble it into a gene but about getting two haplotypes i can't say because then you would need to assess the variants in the region and then mix and match to get the 2 haplotypes but i doubt that'll be of much use or of any significance.

      Check out the software wiki and/or try a Google search of "haplotype from short-read sequencing".

        Thank you for your hint. I think I am going to implement the dynamic programming algorithm described in He et al (2010) and give it a try. I want to assemble only several hundred bases long exons. I think DP should be ok for my problem.

          16S/ITS Profiling vs. Shotgun Metagenomics: What Changes in Your Workflow?
          by SEQadmin2




          NGS has revolutionized clinical microbiology by offering new ways to identify and surveil pathogens without prior knowledge of the target. One popular approach is 16S rRNA and ITS amplicon sequencing, which targets specific microbial markers. But studies are increasingly incorporating shotgun metagenomics, a technique that sequences all DNA from a sample without targeting specific microbial markers. This approach allows more detailed taxonomic classification, detection...

          Multiomic Liquid Biopsy: What DNA/RNA Panels Reveal That DNA Alone Can’t
          by SEQadmin2



          Tumors contain complex mixtures of cell populations that evolve in response to treatment and host-specific factors. Tissue biopsies provide only static snapshots of a tumor’s state. But what if we could follow that evolution over time using a minimally invasive technique?

          Liquid biopsies can detect tumor-derived material circulating in the bloodstream, providing a way to study treatment response, detect emerging resistance, and discover new biomarkers. Circulating
