  • gene tracking in cummeRbund

    Hello,

    I am having difficulty with the makeGeneRegionTrack command in cummeRbund. Below is what happens, after rebuilding the cuffData.db with the gtf file downloaded from the cufflinks website. I'd appreciate any advice on what the problem might be. I've had no problems operating any other cummeRbund commands, so might data is presumably is sufficient and uploaded correctly.

    Thanks,
    SH

    The database appears to be successfully built. I then make and call my gene of interest:

    > head(features(myGene))

    4 NA Insm2 NM_020287 Insm2 P1443 TSS20567


    When I then try to make the gene region track, I get the following:

    > genetrack <- makeGeneRegionTrack(myGene)
    Error in `[.data.frame`(features(object), , featCols) :
    undefined columns selected

  • #2
    I am experiencing exactly the same problem. And I am using the exactly same gtf file as I used for cuffdiff.

      Essential Discoveries and Tools in Epitranscriptomics
      by seqadmin




      The field of epigenetics has traditionally concentrated more on DNA and how changes like methylation and phosphorylation of histones impact gene expression and regulation. However, our increased understanding of RNA modifications and their importance in cellular processes has led to a rise in epitranscriptomics research. “Epitranscriptomics brings together the concepts of epigenetics and gene expression,” explained Adrien Leger, PhD, Principal Research Scientist...

      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...
