  • Error with VelvetOptimiser

    Hello all,
    I'm using VelvetOptimiser.pl from k-mer size 19 to 35 and I got the following errors ;
    Velveth failed! Response:
    1
    mars 2 13:16:55 Velveth with hash value 21 finished.
    Velveth failed! Response:
    1
    mars 2 15:04:23 Velveth with hash value 27 finished.
    Velveth failed! Response:
    1
    mars 2 15:22:32 Velveth with hash value 31 finished.
    I had a look to the source code and that didn't help me :
    unless(-r ($prefix . "_data_$hv" . "/Roadmaps")){
    print STDERR "Velveth failed! Response:\n$vhresponse\n";
    What does " unless -r" mean ? Oo

    Anyway, here's the log file if it can help ;


    User specified velvetg options: -exp_cov 400 -ins_length 400

    Will run velvet optimiser with the following paramters:
    Velveth parameter string:
    -separate -fastq -shortPaired allReads_R1.fastq allReads_R2.fastq
    Velveth start hash values: 19
    Velveth end hash value: 35
    Velveth hash step value: 2
    Velvetg minimum coverage cutoff to use: 0

    User specified velvetg options: -exp_cov 400 -ins_length 400
    Read tracking for final assembly off.

    Beginning velveth runs.

    Please note VelvetOptimiser is still running that's why not all hash failed (not yet ?).

    Are you getting any files produced in any of your velvet output directories?

    If velveth runs successfully you should get 3 files, called Sequences, Roadmaps, and Log.

    Have you tried running velvet without velvet optimiser to check that it is properly installed?

      I only have Sequences and Log but not Roadmaps.

      I'm gonna use velvet withouh velvet optimiser and I give you informer.

        Hello,
        So velvet without velvet optimiser does work.
        Strangly after lauching velvetOptimiser and typping "ps -u" command I get this ;
        PID TTY TIME CMD
        12260 ? 00:00:00 time
        12261 ? 00:00:01 VelvetOptimiser
        12314 ? 00:44:39 velveth <defunct>
        which means velveth was a zombie .... That's very strange oO
        Any ideas anyone ?

        Edit ;
        velvetOptimiser has created several repositories like auto_data_kmersize and I don't know why but some of them contains a Roadmaps file, some on them no...

          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...
