  • VarScan shift in counting of bases!

    I'm using VarScan.v2.2.11.

    The problem I'm reporting here is something about VarScan's parameter --min-avg-qual when using command mpileup2indel. I'm setting it to be default, which is 15.

    In the input pileup file:
    CHROMOSOME_I 221154 g 42 .,,,,,,,+1c,+1c,,+1c,+1c,+1c,+1c,+1c,+1c,+1c,+1c,+1c,+1c,+1c.+1C,+1c.+1C,+1c,+1c,+1c,+1c.+1C.+1C,+1c,+1c,+1c.+1C,+1c,+1c,+1c.+1C.+1C.+1C.+1C.+1C 1C?C<FFFFDHJEAJDJIJG<JJG'GIDIJBD9JDDDG?FDF

    The corresponding output:
    CHROMOSOME_I 221154 G +C */+C:41:8:34:45.33%:4.4044E-13 Pass:11:30:10:24:1E0 0 1 0 0 */+C:41:8:34:45.33%:4.4044E-13

    The red colored part of the input won't get passed the --min-avg-qual filteration, because it's base quality is less than 15. The prblem is that in the output, we see the Cov=41 (which is correct), Reads1=8 (which is also correct), but Reads2=34 (which should be 33, because one of the insertion has mapping quality less than 15).

    Anyone has a similar problem like me? Could anyone help? I think this might be a bug of VarScan.

    Non-Coding RNA Research and Technologies
    by seqadmin


    Non-coding RNAs (ncRNAs) do not code for proteins but play important roles in numerous cellular processes including gene silencing, developmental pathways, and more. There are numerous types including microRNA (miRNA), long ncRNA (lncRNA), circular RNA (circRNA), and more. In this article, we discuss innovative ncRNA research and explore recent technological advancements that improve the study of ncRNAs.

    Recent Developments in Metagenomics
    by seqadmin





    Metagenomics has improved the way researchers study microorganisms across diverse environments. Historically, studying microorganisms relied on culturing them in the lab, a method that limits the investigation of many species since most are unculturable1. Metagenomics overcomes these issues by allowing the study of microorganisms regardless of their ability to be cultured or the environments they inhabit. Over time, the field has evolved, especially with the advent...

    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...
