    remove duplicate reads 100% sequence identity and genomic coordinates

    Hi everyone. I have to analyze some paired end reads coming from a Illumina MiSeq experiment. What I want to do is removing duplicate reads that not only have the same start-end coordinates but also have 100% sequence identity. Is there any tool that can help me do that? I want to work with BAM files not with FastQ files. Thanks!

    If sequences have 100% identity then they should have the same mapping coordinates, so there's no reason to work with bam files in this case. I wrote a program that can do this for fastq, but not for bam:

    dedupe.sh in=reads.fq out=deduped.fq ac=f t=1

    There should be tools that can do so on bam files by sorting by sequence, but I don't know what they are offhand.

      Beyond CRISPR/Cas9: Understand, Choose, and Use the Right Genome Editing Tool
      by SEQadmin2



      CRISPR/Cas9 sparked the gene editing revolution for both research and therapeutics.1 But this system still showed severe issues that limited its applications. The most prominent were the heavy reliance on PAM sequences, delivery limitations, double-stranded breaks that prompt unintended edits and cell death, and editing inefficiency (both in targeting and in knock-in reliability).

      Despite this, “CRISPR helped turn genome editing from a specialized technique into

      Proteomic Platforms: How to Choose the Right Analytical Strategy to Improve Detection and Clinical Applications
      by SEQadmin2


      Proteomics platforms are evolving rapidly, with advances in mass spectrometry and affinity-based approaches expanding what researchers can detect and at what scale. As the field moves toward deeper proteome coverage and clinical applications, scientists face an increasingly complex landscape of tools. This article will explore how researchers are navigating these choices to find the right platform for their work.

      The systematic characterization of the human proteome has
