  • CummeRbund error without CDS

    Hi! I'm trying to run cummeRbund on a cufflinks dataset without a reference annotation of any sort (i.e. just the transcripts assembled from bowtie/tophat results), which leads to my cds.diff being empty.
    Hence, I get the following error when trying to create a cummeRbund database:

    Writing CDS table
    Error in sqliteExecStatement(con, statement, bind.data) :
    bind.data must have non-zero dimensions
    How do I get around this (other than by using a reference annotation)? I'd still like to be able to explore the gene/tss/isoform information?

    Thanks in advance!

    Hi dvanic,
    This has been addressed in the development version of cummeRbund. (now v1.1.3). Please try updating to the new version and see if this resolves this issue.

      Hi loyal Goff,
      I have been trying running CummeRbund. As suggested I installed the latest version of cummeRbund (v1.1.3) within R 2.15.0 . The Error << Error in data.frame(index = c(1:length(samples)), sample_name = samples) arguments imply differing number of rows: 2, 0
      Calls: readCufflinks -> loadGenes -> populateSampleTable -> data.frame
      >>
      disappeared , but a new one showed up as copied below:
      NOTE: my working directory is the ouput directory of cuffdiff. I have to mention that CDS, promoter and TSS files are empty in my case. Only Isoforms and Genes files contain results.

      Thanks for your help.

        Addendum to my previous post:
        I have tried to run cummeRbund both on linux and Windows and got the same error:

        Error in as.data.frame(cast(genemelt, ... ~ measurement)) :
        could not find function "cast"
        Calls: readCufflinks -> loadGenes -> as.data.frame
        Execution halted

          Temp fix

          Hi cristophe,
          This was a bug inadvertently created when I switched to reshape2. I have fixed it for future releases, but for now, the workaround is to import the original 'reshape' library before calling 'readCufflinks':

          Code:
          >library(cummeRbund)
          >library(reshape)
          >cuff<-readCufflinks()
          Let me know if this doesn't work.

          Cheers,
          Loyal

            Hi Loyal,
            That works.
            Only reshape2 was loading automatically and not reshape.
            Thanks
            Christophe

              Current Approaches to Protein Sequencing
              by seqadmin


              Proteins are often described as the workhorses of the cell, and identifying their sequences is key to understanding their role in biological processes and disease. Currently, the most common technique used to determine protein sequences is mass spectrometry. While still a valuable tool, mass spectrometry faces several limitations and requires a highly experienced scientist familiar with the equipment to operate it. Additionally, other proteomic methods, like affinity assays, are constrained...

              Strategies for Sequencing Challenging Samples
              by seqadmin


              Despite advancements in sequencing platforms and related sample preparation technologies, certain sample types continue to present significant challenges that can compromise sequencing results. Pedro Echave, Senior Manager of the Global Business Segment at Revvity, explained that the success of a sequencing experiment ultimately depends on the amount and integrity of the nucleic acid template (RNA or DNA) obtained from a sample. “The better the quality of the nucleic acid isolated...
