  • Problem

    I am new to RNA seq analysis, need help in fixing these problems:

    First, when i am trying to readcufflinks commond i get these errors:

    And when I try Gene Feature plots (makeGeneRegionTrack), it gives this error:
    > genetrack<-makeGeneRegionTrack(myGene)
    Error in `[.data.frame`(features(object), , featCols) :
    undefined columns selected


    Can anyone help me out ??

    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...
