Nevertheless, even if alternative models are worse, they can occasionally result in better refined models than the original initial model. As an example, we consider one of the generated alternative models for TR893 that had a poorer model quality than the original initial model with GDT-HA scores of 70 and 49 for the original and alternative initial model, respectively. However, it turned out that refinement from the alternative model was more successful than refinement from the original initial model (Figure ).
