    Velvet segmentation fault

    Hi All,

    I am trying to run velveth on a cluster to assemble a bacterial genome with illumina data (50bp short reads) and I kept getting segmentation fault error. I tried the test data included in the distribution package, the same error message. What does this tell me? I run Ubuntu 32bit and ssh to a cluster. The velvet is run on the cluster as well.

    Can an expert help me out here? thanks a bunch!

    What's the operating system on the cluster? If I read your post right, you're using a 32-bit OS and running velveth jobs (interactive? Batch?) on a cluster.

    Did you compile on your own machine or on the cluster? Additionally, did you try deleting coredumps, make debug then use gdb and run a backtrace?

      Hi Winsettz,

      the cluster is x86-64. so it is a 64 OS. i downloaded and compiled velvet onthe cluster. I just ran velveth command following the manual on the cluster.

      I am not familliar with deleting coredumps, debugging, using gdb and running a backtrace. Could you give more details how these might help with the problem?

      thanks

        From http://www.ebi.ac.uk/~zerbino/velvet/Manual.pdf

        Reporting bugs: We are very grateful to all the people who send us bugs.
        However, to speed up the process and avoid useless delays, please:
        1. ensure that you have the very last version of Velvet, to the last digit, as
        displayed on the website.
        2. attach to your e-mail the Log file from within the Velvet directory.
        3. if the program crashed and created a core dump file could you please:
        (a) destroy the core.* file
        (b) recompile Velvet with the instruction “make debug”
        (c) re-run Velvet and let it crash (therefore creating a new core file)
        (d) launch the GNU debugger with the instructions:
        > gdb ./velvetg core.*
        (e) within gdb, request a backtrace:
        (gdb) bt full
        (f) send the listing with the entire gdb session.

        What commands are you using for velveth?

          Hi Winsettz,

          Thanks again! I ran "./velveth sillyDirectory 21 -shortPaired data/test_reads.fa" which is copied from the Manual to test. I realized that the test_reads.fa didn't look like paired read data, so tried file type as -short. the same error message. Please refer to the following messages.

          The version I downloaded is the latest.

          Thanks! STuart

            Can you type uname -r on the cluster and gcc -v on the cluster? I've had interesting issues compiling on centos5, velvet 1.2.08 works on centos 6.2.

            Did you try compiling for debug?

              Tried recompile and debug, it doesn't seem to help. Could you take a look of below ? Thanks for your help.
