    CisGenome Issue

    Hello all,

    So i have been struggling a lot with the analysis of some data from ChIP-seq experiment.

    I am a biologist, not a statistician, not an informatician.

    I am using CisGenome for the analysis of my data. When i use the peak caller

    with its default settings, the total number of peaks given is different than the

    total number i get when i add categories of my own [i.e. peaks in promoters, gene deserts, gene bodies, upstream enhancers, downstream enhancers]

    Can anybody tell me why is this happening? It is driving me mad and i can't figure it out. Maybe it's naive but i can't see it.

    Note that when i add my categories of interest, i assign every peak to genes. So could that be it? One peak be assigned on different categories? [i.e. one peak could be assigned both on promoter of one gene and on the upstream enhancer of another gene?]

    Any piece of advise would be greatly appreciated.
    Thnx
    Nick

    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.
