  • 454 data analysis in Qiime1

    Hello
    I analysing 454 data using Qiime1. I have 4 .fna files that seem to be split into 2 forward read and 2 reverse read files. At what point in the pipeline should I combine them? Before demultiplexing? Combine the OTU tables?
    Thanks

    I don't know qiime well (only used enough to know that I strongly prefer mothur). So can't tell you exactly where to combine but you can't combine OTU tables if you do denovo clustering. In mothur, I combined after demultiplexing, sequence qc, and chimera checking but before aligning and clustering into OTUs

        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,...
