    Hi,

    I've tried lots of settings but this is the latest command:
    kSNP3 -in ksnp.list -outdir ksnp-out -k 19 -vcf -NJ -core -ML

    i have 15 genomes with several thousand SNPs. Parsnp runs fine and finds the expected number of SNPs but I cannot get kSNP3.0 to complete.. it always says no snps found. The .vcf output is empty.

    It finishes with this message and hangs:
    Number_SNPs: 1283
    $count_snps: 0
    Finished finding SNPs

    mv: No match.

    Thanks for any help,

    Hi ! I have the same problem here, although it works just fine with two other sets of data.
    Maybe try doing what the previous post on "stuck at tree building step" suggests and check the input files ?

    If your dataset is all of the same species, I'd recommend giving SPANDx a go (https://sourceforge.net/projects/spandx/). If your dataset is all sequence reads then you are good to go but if you want to include assemblies you'll need to convert these to sequence reads first using something like ART. Good Luck!

    Hi
    i have 85 genome, i want to compare the genotypes using kSNP, can someone send me the method and the protocol of comparison from A-Z with a little example please

    thank you

    should i concatenate all the genomes in an one fasta file?

    thank you
