    Selection of indexes

    Hi,
    How to select an optimal set of indexes from different library prep kits to design a sequence run?
    An example: I am about to prepare libraries and sequence 40 samples prepared with XT dual indexing and 21 libraries prepared with single indexes (ScriptSeq).
    Given a set of 8 i7 indexes from the XT libraries the task is to select a set 21 index among 48 available that will differ on at least two positions relative to the 8 i7 indexes.
    It is quite tedious and error-prone to do this manually.
    Does anyone have a piece of script to do this?
    Or how do you select an optimal set of indexes?
    Cheers,
    /Jakob

    Hi again,
    I have made a small R script (attached, "compare_index_Rscript.txt") to compare two lists of indexes (equal index length) and return the number of different positions per combination - thereby making it possible to select the most diverse sets.
    Cheers,

      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
