VIFGC_ovedom function in GenABEL

Question

[kumar.vinod81]

I am using non-additive functions implemented in GenABEL. VIFGC function for dominant and recessive non-additive model is working fine but with the same data, VIFGC_ovedom function is giving an error: Error: Error in nlm(GC_VIF_nlm, c(F = F1, K = K1)) : missing value in parameter

Also, how to calculate phenotypic variance explained by the significant markers in these models.

Thanks,
