By ChimeraX, I am using AlphaFold to predict several protein-protein complexes. These complexes totally comprised about 600-800 amino acids.

To have the predicted results as soon as possible, I would like to ask: 

1: Is there a way to predict only one model(the best one)?

2: what's the advantage of using the Energy-minimized structures?

    Could I just not use it?

 Thanks for your help.
