    Accurate dN, dS estimation from NGS

    Dear all,

    I am trying to calculate Hamming distance, dN and dS values for my data set. The NGS data I am working with contains multiple sequences of varying frequency/read counts. Some may appear 1000's of times, while others might occur 2-3 times. The redundancy has been removed from the final data set and the frequency of the read has been calculated and is given as part of the sequence identifier.

    Can some one direct me to a program or method that will account for the number of times any one read is present in a sample by reading in the read count for the unqiue sequence and incorporating it into the calculation?

    The overall mean sample dN or dS values are greatly influenced by such factors, and I have yet to see a simple application of standard methods to account for this additional information.

    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.
