    Hello from a new RNAseq user

    I just got back my first RNA seq data from a company called Otogenetics. I know a lot about my scientific question but very little about RNAseq results. I've studied tophat, cufflinks, etc. for a few days now but can see that these tools require knowledgeable users. I'm hoping that joining this community is a good first step.

    My application involves analysis of immunomagnetically isolated cell populations compared to the negative (depleted for the selection antigen).

    I paid for some pairwise analyses just to get the ball rolling but can already see that this is a methodology for experts. Cant wait to get rolling on my own workflow: Illumina data->Tophat->Cufflinks->Cuffdiff.

    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.
