[solved] setting cycles

  Hi,

  For the moment, it is not possible to use a variable for setting the number of cycles. You may want to consider the following solution to run a given sequence for a variable number of times:

  1.) Directly append your trial sequence to a block sequence (a block loop is not necessary, because we'll determine the number of cycles ourselves)
  2.) Set the Run-if statement of the trial sequence to 'never'
  3.) Add an inline_script to the beginning of your block sequence

  

  4.) And put something like the following in its Run phase tab:

  # Loop through a cycle of the desired length:
  for i in range(self.get("n_cycles")):
      exp.items["trial_sequence"].prepare()
      exp.items["trial_sequence"].run()
  

  I uploaded an example experiment here (download, change the extension to .opensesame and open as normally):

  Does that make sense?

  works like a charm!
  your solution is very simple and it is now a part of my exp.
  before your replay I managed to do it with "repeat_cycle" - can you see a downside to my solution?
  thank you very much!

  Hi Dror,

  I think your solution is a very good idea! I can't see any advantages for one approach above the other.

  Good luck!
