    SNPeff annotations

    Hi all,

    I have a little doubt about the SNPeff annotations:

    Reading some documentation, I found the list of the Sequence Ontology Terms used to annotate the variants. There are 45 Terms, which are separated according their impact (LOW, MODERATE, HIGH and MODIFIER). I realized that many modifier terms are parents of higher impact terms, for example : the modifier term "coding_sequence_variant" is father of low impact term "synonymous_ variant"

    My question is ¿Why it has to use parent terms ?, I mean, following the example above, if I have a variant that I know is changing a coding region, maybe I will know if that variation is synonymous or not. Why not only use the most down-level term?

    I know there is a reason, but I would like to know.

    Thanks in advance

    Nine Things a Sample Prep Scientist Thinks About Before Sequencing
    by SEQadmin2


    I’m not a sequencing expert. I’m a purification scientist who uses NGS to evaluate workflows my group develops. With this perspective, we think about the sample first and the NGS workflow second. The sequencer is an exceptionally honest reporter, but it can only report on what you give it, so whether you get clean, interpretable data from an NGS workflow is largely determined before you begin.

    Here are nine questions we think about, in roughly the order they matter, before...

    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.
