This is a quality-control tool for genotypes and pedifree. It supports non-renumbered files; you can use this tool before running renumf90.

 Quality control options: --qc {crm,maf,mono,hwe,cra,par,h2gc}
    * crm     call rate for markers
    * maf     minor allele frequency
    * mono    monomorphic markers
    * hwe     Hardy-Weinberg equilibrium
    * cra     call rate for animals
    * par     parentage (Mendelian inconsistency) for markers and animals
    * h2gc    heritability of gene content

  * Set by default. Turn off the option by putting --no- as a prefix instead of --.
    For example, use --no-check-format to avoid checks for the file format.
