The competition has begun! We're giving away a $50 Amazon gift card to the member who answers the most questions on our site during the month. We want to encourage our community members to share their knowledge and help each other out by answering questions related to sequencing technologies, genomics, and bioinformatics. The competition is open to all members of the site, and the winner will be announced at the beginning of July. Best of luck!

    Thanks.

    Unfortunately, it appears as though it was a case of RTFM more carefully. Paired reads have to be in fast-a format if in a single file. I only wasted 2 days because I didn't see that earlier. =/

    It has been a while since I looked at SOAPdenovo, but could you try this config ?
    ----
    #maximal read length
    max_rd_len=100
    [LIB]
    #average insert size
    avg_ins=200
    #if sequence needs to be reversed
    reverse_seq=0
    #in which part(s) the reads are used
    asm_flags=1
    #in which order the reads are used while scaffolding
    rank=1

    issues with SOAPdenovo

    Hello.
    I am wondering if anyone here some some experience with SOAPdenovo.

    I am trying to assembly Illumina data, I have 3 lanes of 101 cycle PE data and 2 lanes of single read data.

    I have tried all sorts of options for running the program down to the default ./SOAPdenovo63mer all -s SOAPdenovo_config.txt -o out_

    At the end of the day (ok, only 2 hours), it is telling me 'no paired reads found' and tossed a terminal error.

    I have used this same data in both CLC and Velvet and it works fine including scaffolding in Velvet and paired mapping in CLC.

    I am sure I am doing something silly. Any thoughts?

    Thanks,
    Bob

    ps. my config file is:

    #maximal read length
    max_rd_len=100
    [LIB]
    #average insert size
    avg_ins=200
    #if sequence needs to be reversed
    reverse_seq=0
    #in which part(s) the reads are used
    asm_flags=1
    #in which order the reads are used while scaffolding
    rank=1
    p=/common/groups/Illx/Genomic_SIPES_lane5_1_paired_trimmed_paired.fastq
    p=/common/groups/Illx/Genomic_SIPES_lane6_1_paired_trimmed_paired.fastq
    p=/common/groups/Illx/Genomic_SIPES_lane7_1_paired_trimmed_paired.fastq
    q=/common/groups/Illx/Unpaired_SIPES_PF_lane5_1_trimmed.fastq
    q=/common/groups/Illx/Unpaired_SIPES_PF_lane7_1_trimmed.fastq
