    DE calculation for RNA Seq

    Hi all
    I am analyzing RNA seq data for DE. We have 2 groups (control & treatment) and sample in each group. We have calculated the RPKM values but not sure how to calculate the Fold change between groups. I was trying to find ratio using the RPKM values but we find huge up or down regulation when the rpkm values between the group are extreme values. Here is an example

    Control Treated Ratio
    Gene A 1.82836 2.57E-09 = 1.41E-09

    In this case the read count for the treatment count is very low when compared to the control. I am not a bioinformatics person so maybe someone could help explaining how to calculate the FC.

    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.
