    edgeR plotting error

    Hello,

    I am analyzing count data from RNAseq and, while I can properly run the differential expression analysis, the plotSmear function fails with the warning

    " Error in log2(x) : Non-numeric argument to mathematical function "

    but when I try to convert the file to make it numeric, I'm told the following

    " Error in lapply(X = X, FUN = FUN, ...) :
    (list) object cannot be coerced to type 'double' "


    Any help would be appreciated.

    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.
