  • Soft clip / trim within unaligned .bam file

    Hi,

    Anyone know of a tool which does soft adapter clipping, quality trimming of unaligned reads in .bam format?

    Thanks

    Not that I know of, but as a workaround, you could convert to fastq and then use Trimmomatic or FastX.

      These won't do soft clipping, however; you'd have to parse their output and do some wild guesswork on the clippings. I would rather take the source and make a fork instead which outputs soft-clipped SAM/BAM.

      @mehc: Do you have an aligner or assembler which accepts soft-clipped bases in a BAM as input? I haven't had that yet (for Illumina data). I've seen aligners soft-clipping bases in the output alignments, however. Or are you writing something on your own and would like to use such information?

        Understanding Genetic Influence on Infectious Disease
        by seqadmin




        During the COVID-19 pandemic, scientists observed that while some individuals experienced severe illness when infected with SARS-CoV-2, others were barely affected. These disparities left researchers and clinicians wondering what causes the wide variations in response to viral infections and what role genetics plays.

        Jean-Laurent Casanova, M.D., Ph.D., Professor at Rockefeller University, is a leading expert in this crossover between genetics and infectious...

        Addressing Off-Target Effects in CRISPR Technologies
        by seqadmin






        The first FDA-approved CRISPR-based therapy marked the transition of therapeutic gene editing from a dream to reality1. CRISPR technologies have streamlined gene editing, and CRISPR screens have become an important approach for identifying genes involved in disease processes2. This technique introduces targeted mutations across numerous genes, enabling large-scale identification of gene functions, interactions, and pathways3. Identifying the full range...
