    SOAP denovo seg faults during map

    Hi all,
    I'm getting a seg fault while running map during a SOAP denovo run. I'm running on OSX with SOAPdenovo v 1.05.
    I have checked to be sure input data has reads larger than 30 bp and that no empty lines exist. Does anyone have any other debugging ideas?

    Here is my cfg:

    max_rd_len=70
    [LIB]
    rank=1
    avg_ins=200
    reverse_seq=0
    asm_flags=3
    q1=s_1_1.fastq
    q2=s_1_2.fastq


    Here's the map execution:

    map -s soap.cfg -g test
    K = 23
    contig len cutoff: 25

    there're 3424 contigs in file: test, max seq len 60625, min seq len 24, max name len 10
    time spent on parse contigs file 0s
    8 thread created
    time spent on hash reads: 1s
    4517379 nodes allocated, 5614229 kmer in reads, 5614229 kmer processed
    time spent on De bruijn graph construction: 1s

    time spent on mapping long reads: 0s

    In file: soap.cfg, max seq len 70, max name len 256

    8 thread created
    5450 edges in graph
    basicContigInfo: 2 vs 3
    basicContigInfo: 3 vs 5
    basicContigInfo: 5 vs 7
    basicContigInfo: 7 vs 9
    ......
    basicContigInfo: 4331 vs 5457
    basicContigInfo: 4333 vs 5459
    basicContigInfo: 4334 vs 5461

    I've been troubleshooting now by trying to divide and conquer. I've been halving the data set to see if i can get one to not seg fault. However, this strategy has really got me scratching my head. I can get the top 1st 1/4 and 2nd 1/4 to get past map. However, the top 1/2 fails. Also, when I concatenate the 1st and 2nd 1/4, it also fails (cmp shows this concat with the top 1/2 are identical).

    Does anyone have ideas??

      Multiomic Liquid Biopsy: What DNA/RNA Panels Reveal That DNA Alone Can’t
      by SEQadmin2



      Tumors contain complex mixtures of cell populations that evolve in response to treatment and host-specific factors. Tissue biopsies provide only static snapshots of a tumor’s state. But what if we could follow that evolution over time using a minimally invasive technique?

      Liquid biopsies can detect tumor-derived material circulating in the bloodstream, providing a way to study treatment response, detect emerging resistance, and discover new biomarkers. Circulating

      New Genomics Technologies Take Aim at Long-Standing Limits
      by SEQadmin2


      Researchers using sequencing and genomics tools often have to make trade-offs. They can choose between speed or scale, short reads or long-range information, or targeted panels or a view of the whole transcriptome. New technologies that have been released this year are built to address those tough choices.

      We asked six companies the same four questions to learn about their latest products. The new technologies bring a lot to the table, including rethinking sequencing
