  • soapsnp segmentation fault - help!

    i downloaded the latest versions of soapAlign, msort and soapSnp today.
    I ran soapAlign and msort (-k n9) no problem.
    But when i ran SoapSNP on the sorted file, i got a segmentation fault.

    Any idea????

    Thanks

    Segmentation fault while using SOAPsnp

    Hi,
    I am using SOAPsnp for the first time. I tried it with bowtie aligned file and ended up with segmentation fault as mentioned below
    ------------------------------
    Reading Chromosome and dbSNP information Done.
    Correction Matrix Done!
    Segmentation fault
    ------------------------------

    I am not sure if SOAPsnp accepts bowtie aligned file or this fault is because of some other reason.
    Any HELP?

      did u figure out this problem.

      I have the same problem of segmentation fault. Did you figure this out now? Somebody told me it may be caused by memory issue. But the computer administrator in our dep. said it is caused by the soapsnp itself. I am lost.

      Thanks.

          try -L option

          soapsnp has a default maximum read length of 45; try using -L to increase this to at least the length of your longest read (e.g. 76).

            Thank you! it works.

            I can see the different base between reference and reads, but I can't get the cell line or strain name for every reads?

            I want to find the SNP between two different strains, how to do it?

              soapsnp still fails for reads longer than 256nt

              Hi!

              I'm trying to build consensus sequence from alignment built using soap.

              Reads were sorted before running soapsnp.

              I defined parameter -L 301 (My longest reads are 301 nt long)

              I still get Segmentation fault after "Processing chromosome XY".

              Thanks for help!

                Strategies for Sequencing Challenging Samples
                by seqadmin


                Despite advancements in sequencing platforms and related sample preparation technologies, certain sample types continue to present significant challenges that can compromise sequencing results. Pedro Echave, Senior Manager of the Global Business Segment at Revvity, explained that the success of a sequencing experiment ultimately depends on the amount and integrity of the nucleic acid template (RNA or DNA) obtained from a sample. “The better the quality of the nucleic acid isolated...
