    Cuffdiff thread option

    Can anyone explain to me the following option in CuffDiff:


    -p/--num-threads <int>
    Use this many threads to align reads. The default is 1.

    What are threads? Will it take longer to run the analysis if multiple threads are used? Will such an analysis be more accurate?

    These are the individual processes that are used by cuffdiff. For example if you have a hyper-threaded core-i3, use -p 4. It uses as much CPU power as possible. So it shortens the analysis time. If you have a 4-core CPU, you are better off using -p 8. It depends on how many thread your processor can handle.

      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.
