    PCoA

    Dear All,

    I have 16s data and have some queries regarding the same.
    I am doing PCoA analysis and Axis 1 and 2 are not showing a separation of sample based on specific factor, so i plotted to axis 3 and 4 which shows sample separation.
    My question is it unfair to choose axis other than 1 and 2 which generally show maximum variance.
    I always assumed that Statistical test will tell you the significant differences and then you can plot any 2 axis which shows the separation of significant factors.
    Sometimes first two axis are not always the correct axis showing the variance for the factor which are found significant p value.
    And that's the reason i changed the axis.
    Please provide me a valuable suggestion to undo my dilemma
    Also if someone have a scientific journal where they too have used other that first and second axis.
    Thank you looking forward for the reply!!

    Love this - good data definitely starts from good input, and poor input can only give relatively poor data. I particularly like the mention of Nanodrop/absorbance based methods for quantification. It's such a toss up if you'll get an accurate reading or what amounts to a randomly generated number, and a lot of library/sequencing related issues can be traced back to poor quant.

    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...
