    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.

    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?

            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!

                      Beyond CRISPR/Cas9: Understand, Choose, and Use the Right Genome Editing Tool
                      by SEQadmin2



                      CRISPR/Cas9 sparked the gene editing revolution for both research and therapeutics.1 But this system still showed severe issues that limited its applications. The most prominent were the heavy reliance on PAM sequences, delivery limitations, double-stranded breaks that prompt unintended edits and cell death, and editing inefficiency (both in targeting and in knock-in reliability).

                      Despite this, “CRISPR helped turn genome editing from a specialized technique into

                      Proteomic Platforms: How to Choose the Right Analytical Strategy to Improve Detection and Clinical Applications
                      by SEQadmin2


                      Proteomics platforms are evolving rapidly, with advances in mass spectrometry and affinity-based approaches expanding what researchers can detect and at what scale. As the field moves toward deeper proteome coverage and clinical applications, scientists face an increasingly complex landscape of tools. This article will explore how researchers are navigating these choices to find the right platform for their work.
