  • Thank you! :-)
  • There are indeed compatibility issues with recent versions of Android. But to know whether that's the issue here, we need to know (as @eduard already says) exactly what happens!
  • As far as I know, there are no such plans. sebastiaan, do you know more? Yes, that was a project that we indeed started a few years ago. Unfortunately we abandoned it. So no, there's no response box sold by OpenSesame!
  • That seems to completely fix the issue. Good! How would you save the acquired data? I've noticed that there is output in the console but is there a more elegant solution other than saving the console output? We do not (currentl…
  • Hi Valentina, That's a a good question. As of v3.2, Canvas elements can have a name, and you can therefore use them to define regions of interest (ROIs). The next question is then how to define ROIs for separate words in a sentence. There are man…
  • Hi Stefan, Is it possible that longer breaks result in such errors? Hmm, I've never seen this, and I don't see how that would happen. But because people rarely take such long breaks it's difficult to exclude the possibility. My first g…
  • Hi Christian, That's an interesting question. The var object has no memory (unlike the responses object). You could give it memory by overriding the way it sets variables, and by adding a function to retrieve a variable's history. Adding the foll…
  • But shouldn't the 'press Q to quit' information disappear when pressing the space bar? Good point
  • Hi Stephan, I think what happens is that the experiment does continue after pressing the space bar, but the window isn't refreshed to reflect this. So then you can get in the situation that the experiment is waiting for a response (without indica…
  • Hi Brice, Do you have multiple Python environments? If so, you may have installed the extension into a different Python environment from the one that OpenSesame is using. And have you checked whether the extension is enabled (Menu → Tools → Pl…
  • Hi Nick, You're running into a weird property of Python 2 (but not Python 3), which is that integer divisions always return int values (and the decimals are discarded). In other words: 5 / 10 == 0 To avoid this, you can add a float somewhere i…
  • Hi Noah, Installing OpenSesame on a Mac is indeed a little bothersome, but it will work. The basic procedure is this (@Daniel correct me if I'm wrong): * Download and open the OpenSesame Mac OS package * Drag OpenSesame onto the application…
  • Hi, My first thought is that you're simply collecting two key presses, for example because you have inadvertently set the duration of a sketchpad to 'keypress', in addition to collecting a key press response during the trial. If that's not it, co…
  • Hi Guerhan, It sounds like you're having trouble opening/ interpreting the log file, but you'll have to be a bit more specific! Could you attach an example data file here? Cheers! Sebastiaan
  • Hi Courtney, I don't have experience with HDF5 files myself, but my understanding is that this is a generic file format that can contains many different kinds of data, and can be read by many different libraries. So there's probably no single bes…
  • Hi Liam, The easiest way to do this is by using a span tag around the words that you want to color, and then assign a special style to them. Like so: red text and green text This is regular HTML, but as of OpenSesame 3.2 this will work als…
  • Hi Brice, This is a separate extension, although it is included by default with the Windows and Mac OS. You can install it with: pip install opensesame-extension-osf Cheers! Sebastiaan
  • Hi Stephan, I'm assuming you're referring to the display scaling, right? (Resolution would refer to the number of pixels on the display.) I'm aware of this issue, and it's super-annoying. For the moment, I don't see any way to resolve this in Ope…
  • Hi Isak, This should be doable, but how depends on the device. More specifically, how do they connect to the computer? It could be, for example, that they work just like a keyboard, in which case you can use a keyboard_response, or that they work…
  • Hi Neo, This happens if you click on the red 'Stop' button (new in 3.2) while the experiment is running. I don't see how you could get this specific message in any other way, because if the experiment crashes you should get a different error mess…
  • @DahmSF Is there something to delete text from a canvas? Yes, as of v3.2 you can have named Canvas elements that you can delete or change without having to redraw the entire Canvas. See: * https://osdoc.cogsci.nl/3.2/manual/python…
  • Is it possible, that perhaps an older version of opensesame would better run? Yes, that's certainly possible. This type of crash generally happens in very specific circumstances, and changing the computer or the version of OpenSesame/ Python…
  • Hi Regina, This type of crash ('Python seems to have crashed') is very difficult to debug, because it's not related to a problem in your experiment per se. This happens when the Python interpreter crashes due to a bug in the underlying libraries.…
  • Hi Tali, I see where this comes from, and I filed an issue for it. Essentially, the response variable is not properly exposed, meaning that the logger doesn't know about it until it has actually been set. So if the form occurs before the first lo…
  • Hi Surya, Thanks for giving OSWeb a shot! As you've probably seen (but just in case), OSWeb is still under development so we don't recommend using it in production. But of course we're keen to fix any bugs. Regarding the crash. Only a limited …
  • I am just in love with Opensesame. Good With Mac someone in my circle reported that Opensesame kept crashing. So they were critizing opensesame. Crashing is a legitimate reason for criticizing a program, so I understand their …
  • Hi guys, There seem to be a few issues in this discussion. The first is that @akca_ece reports needing to press enter to be able to click on the Accept button. This was indeed true with OpenSesame 3.1 and earlier, but as of 3.2 you can use al…
  • Hi Serehal, This sounds like the OpenSesame package has been corrupted for some reason, possibly due to some problem with the package manager. As a first step I would simply reinstall opensesame: sudo apt-get install --reinstall opensesame …
  • Hi Stephan, I've seen this before myself on some systems. As far as I was able to tell, this was due to another program (a Citrix client) that was running in the background and occasionally grabbed the focus, causing the OpenSesame window to mini…
  • Hi guys, Yes, if you use the xpyriment backend in OpenSesame, then you can use all the expyriment routines in an inline_script item. * https://osdoc.cogsci.nl/3.2/manual/backends/#xpyriment Cheers! Sebastiaan
