There are two ways to fit marker based genomic models depending on
whether there are more markers than genotypes.
Fit the model in the marker space if there are more genotypes than markers.
e.g. Yield ~ mu !r Markers
if no genotype replication and < 50000 markers
Fit the model in the genotype space if there are less genotypes than markers.
e.g.
markers.grr !MARKERS 260 !HEAD -1 !SAVE !PEV
FBA.asd !MAXIT 30
H1 ~ mu !r grm1(entry)
if < 50000 genotypes
This build fixes some bugs when fitting the marker model.
