    Problem with ShortRead (R, Bioconductor) function readIntensities

    Hi,

    As I was trying to run Rolexa package for Solexa GAII ChIP-Seq data, I encountered an irresolvable problem already in the initial step: loading the intensity data. I used 'readIntensities' function included in the ShortRead package as follows:

    path = SolexaPath("/data/091029_HWI-EAS419_0050",
    imageAnalysisPath="C1-36_Firecrest1.4.0_02-11-2009_SBSUser")

    int = readIntensities(path, pattern="s_1_0001", withVariability = FALSE)

    ---

    Error: Input/Output
    'readIntensities' failed to parse files
    dirPath: 'C1-36_Firecrest1.4.0_02-11-2009_SBSUser'
    pattern: 's_1_0001'
    type: 'SolexaIntensity'
    error: invalid 'times' argument

    ---

    The path to files is correct, it finds the files:

    s_1_0001_int.txt.p.gz
    s_1_0001_nse.txt.p.gz
    s_1_0001_pos.txt

    It should pick the *int.txt.p.gz file. But something goes wrong. Any suggestions to resolve this are appreciated!

    Hello Maria,

    You should try sending your bug report to the Bioc-sig-sequencing mailing list:


    You'll get help quite fast there from the developers and other advanced users

      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
