What is the difference between overall_best.pdb and cycle_best_1.pdb in the AutoBuild Wizard?
The AutoBuild Wizard saves the best model (and map coefficient file, etc) for each build cycle nn as cycle_best_nn.pdb. Also the Wizard copies the current overall best model to overall_best.pdb. In this way you can always pull the overall_best.pdb file and you will have the current best model. If you wait until the end of the run you will get a summary that lists the files corresponding to the best model. These will have the same contents as the overall_best files.
