    Error running oases_pipeline python script

    Hello!

    I'm very new in the world of bioinformatics, and maybe my question is so simple.

    I'm trying to run the python script for the oases_pipeline, but it always give the same error.

    The command I use is:

    $python oases_pipeline.py -m 21 -M 31 -o outputfolder -d "-fastq -short /Users/geldoc/Desktop/TranscriptomePrograms/velvet_1.2.07/SecondRun/OW_sequence.txt" -p " -cov_cutoff 5 -min_trans_lgth 100 "

    And the error is:

    Could not find Velvet
    Make sure that it is properly installed on your path

    After this, I tried to run velvet without the python script and it works..so I don't understand the error message.... (I checked that the version of oases and velvet are right)

    Thank you very much for your help!!

    Did you determine what the problem was? I am having the same trouble.

      What happens if you try

      $velveth

      from the same directory where you were running the python script?

        I think the problem is being caused by not enough memory. I am rerunning it with the output directory in a virtual directory with greater capacity. Hopefully this does the trick!

          I think you need to change the location of velvet and oases in "subprocess.Popen" section of the oases_pipeline.py script or put the excecutables in /usr/local/bin/ or /usr/bin/

            Love this - good data definitely starts from good input, and poor input can only give relatively poor data. I particularly like the mention of Nanodrop/absorbance based methods for quantification. It's such a toss up if you'll get an accurate reading or what amounts to a randomly generated number, and a lot of library/sequencing related issues can be traced back to poor quant.

            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...
