    How to Repeatmask sequence files >100kb

    I'd like to find out the repeat content (LINES, SINES, LTR-retrotransposons etc) of my Illumina HiSeq sequence Bam files.

    Repeatmasker's online search takes only up to 100kb of sequence and running a local version requires command-line skills (I'm not a bioinformatician).

    Does anyone know of a way to do this without command-line skills?

    Cheers,
    Neil

    I would encourage you to try the command line version because you will have a lot more flexibility and the commands are quite easy. In the simplest case:
    Code:
    RepeatMasker seqs.fas
    Using a custom library for masking is simple as saying "-lib file_of_repeats.fas" and specifying a single species to use for masking is also possible by saying "-species human" to mask human repeats, for example.

      This is where you call upon a friend who has the necessary skills, if you truly do not wish to do it on your own.

      Like SES said this would be simple to do on the command line .. provided you had access to the necessary resources/time to pick up some basic unix skills.

        Thanks guys,
        it seems that I've reached that crossroads, and it is now time to learn some unix.
        Wish me luck.

            Very nice! I was about to post the same link but you beat me to it.

            Note that this is also now a published book you can get on Amazon, or any other bookstore I'm sure.

              Multiomic Liquid Biopsy: What DNA/RNA Panels Reveal That DNA Alone Can’t
              by SEQadmin2



              Tumors contain complex mixtures of cell populations that evolve in response to treatment and host-specific factors. Tissue biopsies provide only static snapshots of a tumor’s state. But what if we could follow that evolution over time using a minimally invasive technique?

              Liquid biopsies can detect tumor-derived material circulating in the bloodstream, providing a way to study treatment response, detect emerging resistance, and discover new biomarkers. Circulating

              New Genomics Technologies Take Aim at Long-Standing Limits
              by SEQadmin2


              Researchers using sequencing and genomics tools often have to make trade-offs. They can choose between speed or scale, short reads or long-range information, or targeted panels or a view of the whole transcriptome. New technologies that have been released this year are built to address those tough choices.

              We asked six companies the same four questions to learn about their latest products. The new technologies bring a lot to the table, including rethinking sequencing
