WOMBAT Example 14

This example illustrates `automatic' GWAS analysis using WOMBAT for
a toy example (simulated data). 

A:  Demonstrates run option --snap. This invokes estimation of SNP effects
    and their standard errors for (co)variances assumed to be known.
    In addition to the data, pedigree and parameter file required for 
    'standard' analyses, it requires a file supplying counts for the number 
    of copies of the reference allele; this has the default name "SNPCounts.dat" 
    and must be (or a link to it) in  the working directory.
    The output file "SNPSolutions.dat" contains estimates of SNP effects, their 
    standard errors and resulting t-values, followed by their p-value derived from 
    the Normal density and log 10 of the latter (one per line).

B:  As A, but for a bivariate analysis (2 traits, fit a single SNP).
    The output file QTLSolutions.dat contains 6 values per line: estimates of 
    the SNP effects for traits 1 and 2, their standard errors and resulting 
    t-values.

C:  As A, but for two SNPs (no p-values).  

D:  Ditto, but two SNPs \& two traits

E:  As A with the addition of `explicit' genetic groups
