[open] Custom Logging/Output

  You'll want to take a look at this discussion, which describes how you can choose custom logfile locations from within an inline_script:

  • http://forum.cogsci.nl/index.php?p=/discussion/740

  In your case, the idea should be the same, but you'll have to make sure that you choose a writable location for the logfile, for example in the /sdcard/ folder (but it's somewhat device dependent). So ...

  path = '%d-%d.csv' % (self.get('subject_nr'), session_nr)
  

  ... might become ...

  path = '/sdcard/%d-%d.csv' % (self.get('subject_nr'), session_nr)
  

  Cheers!

  Thanks! I was able to get it to work based on the previous discussion and your suggested path. Here's the code that ended up working for me:

  #Imports modules for modifying filenames and getting a timestamp
  import os
  import time
  import datetime
  
  # Closes the current logfile
  exp._log.close()
  
  #Creates a timestamp
  rawtimestamp = time.time()
  timestamp =
  #Formats the timestamp into YYYYMMDDHHSS
  datetime.datetime.fromtimestamp(rawtimestamp).strftime('%Y%m%d%H%M%S')
  
  #Version 1 = colored Ps
  #Re-defines the name of the log file as Sub_Sess_TaskVers#_Timestamp.csv
  path = '/sdcard/ChangeDetectionData/Sub' + str(self.get('subject_nr')) + '_Sess' + str(self.get('Session')) + '_ChangeDetectionVers1_' + str(timestamp) + '.csv'
  exp.logfile = path
  
  # Reopens the logfile
  exp._log = None
  exp.init_log()
  
  

  It's working perfectly. I'm curious about something, though. I have a folder with all my stimulus images called TaskImages. In my stimulus display inline, I have the following code.

  Targets=['BA.bmp','BB.bmp']
  #Randomizes which image is first
  shuffle(Targets)
  #Defines the target as the first image (now shuffled)
  trialtarg=Targets[0]
  #Defines the path to the image
  trialtargpath='./TaskImages/'+ trialtarg
  

  But when I try to use a comparable command to define the output folder with a relative path, I get an error.

  path = './VisualSearchData/Sub' + str(self.get('subject_nr')) + '_Sess' + str(self.get('Session')) + '_VisualSearchVers1_' + str(timestamp) + '.csv'
  

  outputs this error in the debug file:
  "IOError: [Errno 2] No such file or directory: './VisualSearchData/Sub0_Sess4_VisualSearchVers1_20140317175935.csv'

  The script currently works great with the original script I attached at the top, so it's not critical, but I'm curious why './VisualSearchData' doesn't work.

  The ./ indicates that the path is relative to the current directory, which (under Android) is the app directory that you don't (usually) have write access to. So it's simply a permissions issue.

  Cheers!
