    HELP!!DEXseq error from DEXSeqResults

    Hi,
    I am using DEXSeq to do alternative splicing analysis. But when I use the test data from DEXSeq's package, I even got an error from the function "DEXSeqResults". I have no idea why this error occurs. Could anyone help me?

    The code I used is shown below:

    > library(DEXSeq)
    > data(pasillaDEXSeqDataSet, package="pasilla")
    > dxd <- estimateSizeFactors( dxd )
    > dxd <- estimateDispersions( dxd )
    using supplied model matrix
    using supplied model matrix
    > dxd <- testForDEU( dxd )
    using supplied model matrix
    > dxr <- DEXSeqResults( dxd )
    Error in (function (cl, name, valueClass) :
    assignment of an object of class “NULL” is not valid for @‘elementMetadata’ in an object of class “GRanges”; is(value, "DataFrame") is not TRUE

    The first step when a bug is encountered is always to update to the latest version of the program available, before reporting the bug.

    Check your version of DEXSeq.
    If it's not 1.16.8, start by updating DEXSeq first.
    Unfortunately, that may involve updating R and Bioconductor.

    Code:
    packageVersion("DEXSeq")
    The second step when reporting a bug in R, is posting your session info, with the bug.

    Code:
    sessionInfo()
    Incidentally, your code works fine for me with DEXSeq 1.16.8.

      Hi blancha,
      Thanks for your reply. Yes, I indeed checked the version of DEXseq and R. Everything is up-to-date shown below:

      > version
      ......
      major 3
      minor 2.3
      year 2015
      month 12
      day 10
      svn rev 69752
      language R
      version.string R version 3.2.3 (2015-12-10)


      > packageVersion("DEXSeq")
      [1] ‘1.16.8’

      I searched online and didn't find the solution to this problem. You have some other ideas? Thanks!

        You presumably have an outdated dependency. What you tried works for me without an error. My setup is below:

          I agree with dpryan.
          sessionInfo() will give more details about the attached packages.
          Check which packages differ from our setup.
          Perhaps you just need to update GenomicRanges.
          In the worse case scenario, you can just update everything or reinstall everything.
          The code works fine for me.

          Code:
          > library(DEXSeq)
> data(pasillaDEXSeqDataSet, package="pasilla")
> dxd <- estimateSizeFactors( dxd )
> dxd <- estimateDispersions( dxd )
using supplied model matrix

> dxd <- testForDEU( dxd )

> dxr <- DEXSeqResults( dxd )

            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.
