  • FreeBayes not standard haplotype calling

    Dear,

    It's the first time I'm trying to perform this type of analysis, and I'm not in a standard situation. Here's what I have.

    I have a:
    - Metagenome reference. Each contig of the reference is a haploid genome
    - All samples were pooled together and subsequently sequenced with MiSeq partially overlapping reads (˜80%). Each read is 300bp.

    What I did:
    I mapped those reads without merging them onto the reference.

    I'd like to:
    Call for haplotype in order to estimate the divergence of lineages for each contig of the reference.

    In order to do that I'm trying to use freebayes, but I don't know exactly which parameters I do have to set. For example, I know the genomes are haploid but I don't know how many individuals I have in the pooled sample, so I'd like to call as many variants as freebayes is able to call, definitely not only the biallelic once.

    Any advice?

    Thanks a lot
    F

    Genetic Variation in Immunogenetics and Antibody Diversity
    by seqadmin



    The field of immunogenetics explores how genetic variations influence immune responses and susceptibility to disease. In a recent SEQanswers webinar, Oscar Rodriguez, Ph.D., Postdoctoral Researcher at the University of Louisville, and Ruben Martínez Barricarte, Ph.D., Assistant Professor of Medicine at Vanderbilt University, shared recent advancements in immunogenetics. This article discusses their research on genetic variation in antibody loci, antibody production processes,...

    Choosing Between NGS and qPCR
    by seqadmin



    Next-generation sequencing (NGS) and quantitative polymerase chain reaction (qPCR) are essential techniques for investigating the genome, transcriptome, and epigenome. In many cases, choosing the appropriate technique is straightforward, but in others, it can be more challenging to determine the most effective option. A simple distinction is that smaller, more focused projects are typically better suited for qPCR, while larger, more complex datasets benefit from NGS. However,...
