  • ssaha and bwa-sw vs. bowtie/bwa...etc

    For an educational and practical perspective, the question here has been teasing me for a satisfying answer as it has been a subject of a lengthy discussion between my superiors and I was pushed into it to give them a satisfying answer.

    Let's have this simplistic background; If we make a distinction between Sanger and NGS sequencing techniques that the main difference is that the later is hugely parallel (fastq files for both techniques can be obtained). And if we make another distinction between short read and long read mapping tools and that the later aren't hash based and employed in analyzing NGS platforms data but not that data produced by traditional Sangers (capillary based sequencing).

    Now, the question is, given that the fastq files generated by either NGS or Sanger platforms will still have quality scores that are phred based, what essential differences exist if I use bowtie for example to map sequences produced by a sanger platform ? (if those sequences were shorter than 200 nts)

    Choosing an appropriate mapping tool is paramount of course however, I don't fully comprehend why I will have to say use SSAHA2 on Sanger data as opposed to the faster bowtie...

    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,...
