  • tophat running error

    hi All

    I have installed the tophat with bowtie and samtools in the path but I am getting the error when I try to run the example file.
    [2012-07-25 17:31:11] Beginning TopHat run (v2.0.4)

    Can any one help me in correcting this.

    Well, did you check to see if the file exists? E.g., /usr/lib64/python2.6/subprocess.py. If not then you will have to get it installed.

      Did you find a solution for this? I am getting the same error.

        Perhaps the response I gave figo1019 worked? How about for you, rpauly? What does an

        'ls -l /usr/lib64/python2.6/subprocess.py'

        give?

          Running 'ls -l /usr/lib64/python2.6/subprocess.py' Gives me:

            rpauly: You are running this using partek flow software so this error may be best addressed by contacting Partek tech support. have you tried to contact them?

              No, I just put the files in the flow directory but I am running it using the command line tophat option.

                Are you using tophat that is part of partek flow install?

                  Now that I look at the Python code (subprocess.py) it is simply complaining about a missing data file. What file it, all too naturally, does not say. :-(

                    Never mind...fixed it!
                    samtools was not in the path...

                    Thanks everyone!

                      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 on Modified Bases...

                      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...
