Hello all, I am getting confused by the runCommand() functionality when I am trying to run scripts. When I run my python script through IDLE(From Tools-General), the ouput of runcommand commands like rmsd etc are given the IDLE. I want to store the output from runcommand into a variable dynamically. I dont want to save from the ReplyLog (by running program without IDLE) or output to file, is there something in python itself that I am not understanding and hence, not using, or is it not possible to store the output of runcommand into a variable/list etc, as it is possible for the midas.rmsd function for example. I only ask because I prefer to use the command line functionality over the midas command. If it is only possible with the direct midas, how do I find out the equivalent command of the runcommand for the midas python formatting? Thank you Sorry if my question is a bit confusing!
