    RNASeq - overrepresent sequences

    Hey guys!

    First of all, I'm sorry If I'm puting this question in the wrong section, but I'm new to this forum.

    Well, I'm doing DE with RNASeq and after doing some QA and QC (removed the solexa adapter and trimmed the reads) I still have an 2 overrepresented sequences from most of my fasta files, which are:

    CGATGAAGAACGCAGCGAAATG

    CCCCCTGGAATACCAAGGGGCG

    Do you have any idea what they are?

    Thanks a lot!

    Were any PCR primers used in preparing the sample?

      Hi!

      Actually I'm not sure. But background is not biological, but I tried looking in the article and suplementary material, but I didn't find anything.

      This is the article:

        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.
