    Scripture doesn't recognize CIGAR string.

    Let me describe my problem with an example.

    This is my sorted, indexed sam file.
    seq.2851795 89 1 4470815 255 49M98N29M2S = 4470815 0 TGTGTGTGTGTGTGCGCGCGCGTGTGTGTGTGTGTGTGTGTGTGTGTGTGTGTGTGTGTGTGTGTATGTGTATGTGTGCG @@@DD@DDGDDFHGFHHGGIIEGGADBHIIIIIDEIIIHIIJGHEEGHGGHFEFDCC18/=/;;@)0&8>?@>B&25<98 OL:A:IH:i:1 HI:i:1

    When I run Scripture on this with appropriate size information and reference genome, I got this error.

    Using Version VPaperR3
    Has pairs: false
    Has upweighting turned on: false
    Computing weights..... upweighting? false weight: 1.0

    Got read iterator
    Made it through all reads
    Collapsed reads

    at broad.pda.seq.segmentation.ContinuousDataAlignmentModel.main(ContinuousDataAlignmentModel.java:2209)

    But when I change the 5th column (the CIGAR string) into 80M, it works and returns a result.
    Scripture's web page says it takes in a `spliced read alignment', and my input indicates that it is a spliced read alignment. Then what's wrong in my file?

    FYI, I used both of the working version of Scripture (scripture-beta.jar and scripture-beta2.jar)
    Thanks in advance,
    HJ.

    Reply to Nine Things a Sample Prep Scientist Thinks About Before Sequencing
    by GATTACAT
    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...

    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.
