Hi, I would like to write a script that executes "alphafold predict SEQUENCE" and then postprocess the results. The script would be similar to: from chimerax.core.commands import run run(session, "alphafold predict %s" % sequence_data) # wait until alphafold is done # and postprocess the file best_model.pdb but I do not know how to implement the part "wait until alphafold is done" if, after launching alphafold, I create a loop similar to: === counter = 0 current_size = _getSize(file_path) while current_size !=_getSize(file_path) or _getSize(file_path)==0 or not os.path.exists(file_path): current_size =_getSize(file_path) time.sleep(60) counter += 1 if counter > 240: # break after four hours if file is not created break ==== the loop is executed as soon as the alphafold command has been sent to google, the alphafold-colab window is not shown until the loop is finished and therefore, alphafold execution never starts. So the question is: how can I write a script that waits until the command "alphafold predict ..." finishes and then executes some code. Thanks Roberto
