    TruSeq exome capture.... FYI we saw it in rna seq data also!

    Contamination in my sample?

    Hi all!

    I just ran a 100bp PE human exome seq run in my lab and was looking at the fastqc results of my run. I am getting this weird pattern in the gc content distribution and was wondering is this normal for an exome run or do i have some sort of contamination? I've run an exome seq before in my lab but saw a distribution which was similar to the theoretical distribution with a shorter peak (yet, still normally distributed). The 2 peaks i'm seeing in the new run is really messing with my head as i have 24 samples all showing the same pattern!

    Thanks in advance!

    From Collection to Sequencing: Why Sample Preparation and Preservation Define Sequencing Data
    by SEQadmin2


    Data variability is still an issue in sequencing technologies despite the advances in reproducibility and accuracy of these platforms. But the problem does not originate in the sequencing itself, but in the previous steps, before the sample reaches the sequencer.


    The first step is collection, followed by preservation and sample preparation for analysis. Most scientists overlook those steps, but not being careful might just be skewing the experiment’s results.

    Environmental Genomics in the Age of NGS: From Microbes to Conservation Strategies
    by SEQadmin2

    Studying ecosystems means dealing with complex, multi-species communities that are hard to observe at scale. This complexity, however, hides many important questions to be answered, from how biogeochemical cycles work and how climate change can affect species distribution to how conservation strategies can work best.


    Genomics, particularly since the expansion of NGS, has transformed ecosystem ecology. By sequencing environmental DNA, we can now assess biodiversity without direct...
