[solved] Two separate Log files

  Hi Vivi,

  No, I'm afraid not. If you want to maintain a separate log-file, you have to use a bit of inline code. Nothing terribly complicated though.

  At the start of the experiment, open the logfile like this:

  global myLog
  myLog = open('mylog.tsv', 'w')

  At the end of each trial, log responses (or any arbitrary string) like this. The chr(10) is an end of line.

  global myLog
  myLog.write(str(self.get('response')) + chr(10))

  At the end of the experiment, close the logfile:

  global myLog
  myLog.close()

  Of course, you can handle custom log-files in a ton of ways. This is just an example. For more info about Python file objects, see http://docs.python.org/tutorial/inputoutput.html#reading-and-writing-files

  Hope this helps!

  Cheers,
  Sebastiaan

  Thanks, Sebastiaan. That does help. Except, now I have one issue. It is logging each response twice. Why is that?

  EDIT: Solved. It is interesting how you can play around with all of the scripts and can figure out what is wrong. I had input the script in both the prepare and the run phases.

  Also, in the inline script, is there a way to designate in the file name a subject number which automatically changes for every new subject I run? Or would I have to go into the inline script and add a number in my file name every time I run the experiment with a different subject?

  Sure, you can access the subject number as the subject_nr variable. (also see this post)

  So you can create a filename that the depends on the subject nr like this:

  global myLog
  myLog = open('mylog-%d.tsv' % self.get('subject_nr'), 'w')

  Cheers!

  Thank you, Sebastiaan. Everything works well now.
