  • TopHat juncs file

    Hi,
    How to supply tophat with a list of raw junctions?
    Actually I have a set of splice junction set generated using refFlat and Solexa pipeline's splice_sites.pl. How do I convert it to raw-juncs file.

    How to generate GFF3 files for human as well as mouse?

    building a GFF3 file isn't a very straightforward process. for me it involved doing a bit of work at the command line including installing some Python libraries and downloading code from a CVS repository. you might want to just wait until Tophat supports GTF files which I understand is coming soon. GTF files can be downloaded straight from the UCSC Genome Bioinformatics Table Browser.

      Hi,
      This post is almost a year old. I am caught in the same situation and was wondering if someone has already written a script to convert refFlat to GFF3 format that I can use here.

        I am curious to hear as well...

          Convert UCSC Genome Browser-format gene files into GFF3 version files.
          Only the gene IDs and their locations come through. You have to get
          the comments and aliases some other way.

            It seems that the latest version of TopHat (1.1) allows you to use GTF files, which are more easily obtained. There is at least one other post I've seen detailing how to do that.

              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...
