  Hi,

  You can bypass the startup menu of the OpenSesame runtime for Android by creating an opensesame-autorun.yml file as described here (new in 2.9.5):

  • http://osdoc.cogsci.nl/getting-opensesame/android/#automatically-start-an-experiment

  This will always start the experiment with the same logfile, but you can reopen a new logfile at the start of the experiment as described here:

  • http://forum.cogsci.nl/index.php?p=/discussion/comment/4745#Comment_4745

  Does that help at all?

  Cheers,
  Sebastiaan

  Hi Sebastiaan,

  Thank you for the answer, bypassing the menu works like a charm with the .yml file. If anyone else wants to use it: it only works if the experiment is saved as a .opensesame file and not as .opensesame.tar

  The second part, incrementing the file name by one and use this as a new log file, has not worked for me yet. This is what i want to use in the beginning of the experiment:

  import codecs
  import os
  
  exp._log.close()
  
  i = 1
  while os.sdcard\Data.exists("subject-%s.csv" % i):
      i += 1
  
  exp._log = codecs.open('subject-%s.csv', 'w', encoding='utf-8')
  

  So it opens the latest log file that has been created. Unfortunately, this does not work. I wish i could copy the debug-file but for some reason the windows explorer crashes whenever i try to open/copy/delete a .txt file from the Nexus 7 (is this a known problem?).

  EDIT: This is the same debug file but generated from my laptop:

  Starting experiment as ExperimentProcess-6

  The error message is gone now but log file does not work properly since it does not update the new file. When i run OpenSesame on the tablet it automatically starts the experiment. This is what is have at the start of the experiment to close and re-open the current logfile with a newly assigned subject number.

  import codecs
  import os
  
  # Close current log file
  exp._log.close()
  
  # Define the first log
  i = 1
  while os.path.exists("subject-%s.csv" % i):
      i += 1
  
  # Open the new log file with up to date participant number
  exp._log = codecs.open('subject-%s.csv' % i, 'w', encoding='utf-8')
  

  During the experiment is use the default logger with two variables. But there is no new .csv file written nor any error. Can anyone see what i'm doing wrong here? Could it be that the logger item does not acknowledge the new log file?

  Hi,

  You don't specify a folder, so the logfile is created in the working directory. To be honest, I don't know what that is for an Android app, but it's probably some internal, hidden folder.

  Does it work if you explicitly specify the logfile folder? Here I used /sdcard/:

  import codecs
  import os
  
  # Close current log file
  exp._log.close()
  
  # Define the first log
  i = 1
  while os.path.exists("/sdcard/subject-%s.csv" % i):
      i += 1
  
  # Open the new log file with up to date participant number
  exp._log = codecs.open('/sdcard/subject-%s.csv' % i, 'w', encoding='utf-8')
  

  Cheers,
  Sebastiaan

  Hi Sesbastiaan,

  Thank you for the reply. I managed to get it to work now by specifying the folder and changing the input from string to decimal. I also created a manual logger instead of the standard item because the files were starting to get messy.

  I guess the earlier log files are written to /data/data/nl.cogsci.opensesame which is indeed a hidden folder.

  Anyway, the workaround allows for much more efficient data gathering, so thank you for the help!

  Cheers,

  Laurent

  Hi Sebastiaan and Laurent,

  I would love to find a way to bypass the "Enter subject number" dialogue box (so participants don't have to input a subject number manually), change the text the dialogue box contains (so I can replace with my own more specific instructions), or apply default subject numbers that are not 0 for each run. I use the regular OpenSesame (not runtime) on a PC. Do you know of any ways to do any of these things?

  Thank you so much,

  Jessica

  Hi Jessica,

  With the regular desktop application this is not possible, but opensesamerun allows you to specify the subject number and log file on the command line, like so:

  opensesamerun my_experiment.osexp -s 0 -l logfile.tsv
  

  Cheers!
