[solved] 'File does not exist' error for a file that is in the file pool

  Hi Grusha,

  This doesn't sound like an obvious programming error. One question, does the experiment crash during the same sound files each time? Or does it crash sometimes when trying to play a file, that you know worked in a previous experimental run?

  Well, if your experiment is as large as "thousands of files" suggest, uploading it, might indeed be tricky. Maybe it will be enough if you only include a subset of images? You can use www.filedropper.com for example.

  Hope this helps.

  Not sure this is of any help, but:
  I had the same error and it turned out to come from a 'run if' statement. I have a form that should only appear after a certain item, so under 'run if' I put sth like

  [item]=01_verb_0.wav

  That caused the error, whereas with

  [item]="01_verb_0.wav"

  it works just fine. (I don't know if the file name starting with a number was part of the problem.)

  As I said it seemed to only concern the 'run if' thing, so I'm not sure it applies to your problem in anyway.

  Thanks for this suggestions. In your case, what was the issue is that Opensesame interpreted 01_verb_0.wav as a variable, not as a string. So that it threw the error, because it could not find the variable anywhere. Once you changed it to "01...0.wav", it read it as string and did the comparison with the plain string, just as you wanted it to be done.

  I doubt that this is reason why grusha has the issue, though.

  Thanks for your replies! For the files that weren't working, I loaded the file into the file pool and then copied the file name from there. Then it worked. So my theory is that, there might have been a space at the beginning or something else that I missed! Sorry about that!!

  However, just for future reference, is there any way to check to see if all the file names mentioned in the list actually exist in the file pool without running it? (In this case, my experiment is 3 hours long and I tested out chunks in other blocks before.. But I still had to in some manner run through all the files and also the experiment to be verify it..) Also is there any way to run an experiment from a particular point? So far I have been using the GUI largely and couldn't figure out a way to do it. But if you have any suggestions using python scripts I would really appreciate it!!

  Hi Grusha,

  If you use Opensesame 3.0, you can simply try print pool.files() in an inline_script to check whether a file is in the file pool.

  Hope this helps.
