[chimerax-users] Only retrieving the first predicted model in AlphaFold?

Hi: 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. backy
