    Sicer questions

    I am using Sicer to examine data from DNMT1 binding by ChIP-seq. I run IP and input and want to know
    1) what is the ChIP island Read Count and Control island read count and how are they calculated.
    2) Are these data normalized or do I need to do this separately if I have multiple samples? If the answer is yes- what do you recommend?
    3) What are the redundancy raw reads (filtered by islands) and
    4) Does anyone know of a ChIP-seq paper that has recently used this approach?

    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...
