    TopHat running error

    Hi,
    I found the same problem of boahua100 while running tophat. I moved the executable files bowtie, bowtie-inspect e bowtie-build in the same path where tophat, the reference file and the reads file are but:

    student@410083:~/Desktop/tophat-1.0.9/PROVA$ ./tophat -o GINO -m 2 -G pizzolo.gff Scaffold_bowtizzato Reads1

    [Thu Jul 23 18:09:15 2009] Beginning TopHat run (v1.0.9)

    Any suggestions?

    Thanks!!

    Hi,
    I was ever met such errors.This happens when you don't put bowtie in your PATH.

      Thanks,
      I checked again and bowtie was not in the PATH..Now I put it there and TopHat correctly works.

        Nine Things a Sample Prep Scientist Thinks About Before Sequencing
        by SEQadmin2


        I’m not a sequencing expert. I’m a purification scientist who uses NGS to evaluate workflows my group develops. With this perspective, we think about the sample first and the NGS workflow second. The sequencer is an exceptionally honest reporter, but it can only report on what you give it, so whether you get clean, interpretable data from an NGS workflow is largely determined before you begin.

        Here are nine questions we think about, in roughly the order they matter, before...

        From Collection to Sequencing: Why Sample Preparation and Preservation Define Sequencing Data
        by SEQadmin2


        Data variability is still an issue in sequencing technologies despite the advances in reproducibility and accuracy of these platforms. But the problem does not originate in the sequencing itself, but in the previous steps, before the sample reaches the sequencer.


        The first step is collection, followed by preservation and sample preparation for analysis. Most scientists overlook those steps, but not being careful might just be skewing the experiment’s results.
