Dear all,
I was fitting an animal model including GIV for my simulated data and I
had the following message:

2 singularities, 0 negative_pivots in G matrix of order 422
obtained from ibd.grm
   133 4
 Determinant -327.3353
 Fault 0 Error reading ibd.grm

Can somebody please explain the situation and how to solve that problem.
Many thanks for any reply.
