  Hi Evt,

  Welcome to the forum and thank you for your interest in OpenSesame!

  I'm afraid I don't fully understand the question. Do you want to:

  • Ask a number of questions, which are the same for all participants, but in randomized order

  • Collect text input from participants

  • Present a picture with each question, which is held constant (i.e., the same with each question) for each subject, but varied between subjects (i.e., each subject has a different picture).

  Is this correct? If not, could you provide some more details about what you want to do?

  Kindest regards,
  Sebastiaan

  Dear Sebastiaan,

  I want to display dialogues to my participants (and have them read parts of them).
  Any way I can display .txt files full screen... directly or indirectly...

  i mean... i could, of course, just screen-shoot them and display them as images... but maybe there's a better way?! in-line coding solution?!

  warning disclaimer: user not experienced with programming.

  thanks!

  Hi Stoph,

  Sure, you can read the contents of a text file into a variable, and then show the variable using a text_display item. Let's assume that you have a text_display item that shows [my_text], i.e. a variable called my_text. You can then add the following code to the prepare phase of an inline_script at the start of the trial_sequence. This reads the contents of a file my_text_in_pool.txt (assumed to be in the file pool) into the variable my_text.

  For more information, see:

  • http://osdoc.cogsci.nl/python-inline-code/experiment-functions#experiment.get_file
  • http://docs.python.org/tutorial/inputoutput.html#reading-and-writing-files

  path = exp.get_file('my_text_in_pool.txt')
  text = open(path).read()
  exp.set('my_text', text)

  Cheers,
  Sebastiaan
