[solved] inline script logging fails

  Hi,

  What you are doing with the exp.set function is making a variable on the OpenSesame GUI level. This does not actually log the variable, nor it's value! What you probably want to do, is use the inline_script's self.log function. See here for it's documentation.

  In your case, this would result in something like the following:

  # log to experiment
  def logToExperiment():
      for x in toneStartLog:
          print 'toneStartLog', x
          self.log('ToneStartTime_RTT,' + str(x))
      for x in strokeResponseLog:
          print 'strokeResponseLog', x
          self.log('strokeResponse_RTT,' + str(x))
      for x in responseTimeLog:
          print 'responseTimeLog', x
          self.log('responseTime_RTT,' + str(x))
      self.log('keyStrokes_RTT,' + str(keyStrokes))
      print 'keyStrokes', keyStrokes
  

  This wouldn't result in the prettiest log file ever, but you can of course think of other ways to do this! Another option is to create your own logfile:

  # open log
  exp.my_log = open('custom_log_%d' % self.get(subject_nr), 'w')
  # write header to log
  exp.my_log.write("var_a,var_b,var_c\n")
  # write some random values to log
  for i in range(3):
      exp.my_log.write("%d,%d,%d\n" % i, 2*i, i+3)
  # neatly close log
  exp.my_log.close()
  

  Good luck!

  Hi Edwin, thanks very much for the answer and help.

  Yes i saw the possibility to log text, but this indeed would result in a non-handable logfile for later analysis.

  My initial question was aiming at if it is possible log with loops, in this case I would have thought every assignment of a variable would be a new line in the log file but this is unfortunately not the case.

  i ended up logging every single value to a variable (attaching a logger).

  exp.set('responseTime_RTT1',responseTimeLog[0])
  exp.set('responseTime_RTT2',responseTimeLog[1])
  exp.set('responseTime_RTT3',responseTimeLog[2])
  (...)
  

  As a complete logfile with the other variables from the experiment is prefered, this solution is not pretty but acceptable.

  I guess I just did not completely understand the logging concept of OS

  Thank you very much!
