Not enough information to compute CE-stat

    Hi
    I have installed metassembler and the testdatset runs through smoothly
    Now I tried to run it on two genome assemblies using the config file below but keep getting this error
    sys.exit('ERROR: Not enough information to compute CE-stat for %s.\nread1=%s\nread2=%s\nmaxins=%s\nminins=%s\n' %(read1,read2,maxins,minins))
    TypeError: not enough arguments for format string

    ALl used pathes are fine, input files are also fine (fastq files are correct), I checked the parameters for the config file in the manual and I cant find what I am missing here
    All dependencies work fine as well since the test dataset went through without any issues.

    Metassemble configuration file suggested template

    [global]

    Mate-pair mapping parameters:

    bowtie2_threads=8
    bowtie2_read1=all_1P.fastq
    bowtie2_read2=all_2P.fastq
    bowtie2_maxins=1000
    bowtie2_minins=0
    genomeLength=950000000
    meta2fasta_keepUnaligned=3
    meta2fasta_sizeUnaligned=350 350
    nucmer_l=50
    nucmer_c=300

    CE-stat computation parameters:

    mateAn_s=500
    mateAn_m=350

    [1]

    fasta=celera/all_females.scf.fasta
    ID=CeleraFemales

    mateAn_file=

    [2]

    fasta=/spades/scaffolds.fasta
    ID=SpadesFemales

    mateAn_file=

    I solved the proble, metassemble needs a value bigger than 0 for bowtie2_minins (apparetntly) whereas the bowtie2 manual page says 0 is default
    -I/--minins <int>

    "The minimum fragment length for valid paired-end alignments. E.g. if -I 60 is specified and a paired-end alignment consists of two 20-bp alignments in the appropriate orientation with a 20-bp gap between them, that alignment is considered valid (as long as -X is also satisfied). A 19-bp gap would not be valid in that case. If trimming options -3 or -5 are also used, the -I constraint is applied with respect to the untrimmed mates.

    The larger the difference between -I and -X, the slower Bowtie 2 will run. This is because larger differences between -I and -X require that Bowtie 2 scan a larger window to determine if a concordant alignment exists. For typical fragment length ranges (200 to 400 nucleotides), Bowtie 2 is very efficient.

    Default: 0 (essentially imposing no minimum)"
