Hi @jing , In OSWeb, the loop items do not use a DataMatrix, but a custom JavaScript object. In principle, you can access this also programmatically. Say that you want to print out the 'matrix' for an item called block_loop: console.log(this.experim…

Hi @LBell4291 , Based on your description I suspect that you haven't specified the extension for the filename of the image. Probably, your images aren't called image33 etc., but image33.jpg or image33.png . If that's indeed the issue, then adding …

Hi @deandgei , These scripts replace the condition column in the block loop (so this column should be removed from new_loop), and the second script should be at the start of each trial, so at the start of trial_sequence_1. Looking at your loop tabl…

Hi @BudSpencer , The error message indicates PyGaze cannot connect to the device. There can be many reasons for this, but the most likely one is that the EyeTribe server, which is the software that PyGaze connects to, is not running. Or perhaps the …

Hi @deandgei , Loop constraints are not supported in OSWeb, as you probably noticed. So you need to write a script that applies these constraints for you. The general logic is always the same: Create a list (or array in JavaScript) of conditions Shu…

Hi @sudarshanj , OpenSesame 0.27.1 is eight (!) years old, and I wouldn't recommend using this version anymore. I suspect that you can install the latest version of OpenSesame (3.3.9 at the time of writing) also on Raspbian OS through Anaconda, whic…

@TOS21 That's perfect, thanks! I elaborated on this in this discussion.

Hi @tansu , It looks like the file is corrupted, i.e. it is not a valid OpenSesame experiment file. This can happen for any number of reasons. Maybe you can upload it here and then I can see if it can be recovered? Alternatively, you can also see if…

Thanks @kri and @elisa ! I added some information about this to documentation. https://osdoc.cogsci.nl/3.3/manual/counterbalancing/#using-batch-session-data-jatos-and-osweb-only Imagine somebody wants to test 300 people.. it will be annoying to have…

Hi @mbcerul4 , The experiment will run for a certain number of loops (around 11 loops out of 20), then an error will appear "Status_Access_Violation" and it will fail. Do you see a more detailed error message in the developer console? http…

Hi @Ari422 , Ah I see! The error message basically says it all: you've listed 'none' as one of the allowed keys in the keyboard_response items, but there's no such key. (On the desktop this doesn't give an error because the desktop runtime simply i…

Hi @Ari422 , If the file is too large, maybe you can create a smaller and simplified version that shows the same problem? And then post that here? — Sebastiaan

Hi @Sannee , Good to hear that you figured it out! Indeed, although the goal is to have experiments run in exactly the same way on the desktop and in the browser, the reality is that there are subtle differences, including the names of certain keys.…
-
Hi @Sannee , The numpad keys are called kp0 , kp1 , etc. This is not obvious or documented properly, but you can see the list of valid key names here. You mention that you've tried kp0 , but that this did not allow you to type in anything. My first …

Hi @kri , Thanks for this explanation. I think I understand it better now. It's more complex (but also more elegant) than I initially thought. I attached an experiment that, at the start of the session gets the first element from the pending array.…
-
Hi @Ari422 , Before you run an experiment in a browser, you should first check whether you're not using any functions that are not supported by OSWeb. https://osdoc.cogsci.nl/3.3/manual/osweb/osweb/#supported-functionality If you're confident that y…

Hi @Jaiden_Camryn , You can go ahead indeed, but it would be even better to update to 3.3.9! This also has some useful improvements to the OSWeb compatibility check. — Sebastiaan
-
Hi @Ari422 , This error is related to OpenGL, which is the library that is used for display presentation (by the psycho and xpyriment backends at least). I don't know exactly what this error means, but the fact that it appears now and not before sug…
-
Hi @Jaiden_Camryn , What version of OpenSesame and operating system are you using exactly? It also interesting to note that this happens only when launching the desktop open sesame study and not when using osWeb which I intend to use for this study.…

Hi @SINE , Good to hear that you figured this out, and thanks for sharing! — Sebastiaan
-
Hi @anabatista , The error message is quite confusing, but it results from the fact that the file names of the sound files don't have a file extension that indicates that they are .wav files. If you rename Correct answer to Correct answer.wav and W…
-
@kri Ah, it seems you're right. I don't think this is of much use @TOS21 right now (because it would still take a fair bit of programming to accomplish this), but this might open the possibility of allowing remote URLs for stimuli (sound and images)…
-
Hi @janhoruk , The font size is indeed set to 105% in the css, which is odd, but actually doesn't affect the experiment, because this renders text differently. (You can try this by changing the font-size property through the browser development too…
-
Hi @jara , The background script, with which I assume you mean the script that defines an experiment and the items in it (?), is simply not written in Python, but in a simple scripting language called OpenSesame script. That's what you're seeing whe…
-
Hi @TOS21 , In principle, in an inline_javascript you should be able to read an audio sample from a URL (using fetch() ) and play it (using an AudioContext ). However, this will take some figuring out (I have never done this myself), and you're al…
-
HI @Fab , If you go to Preferences → Running experiments and select "Run experiment in a separate process", does the error go away? — Sebastiaan
-
Hi @DamianoG , OSWeb calls jatos.appendResultData() every time that a logger item is executed. This ensures that the data is logged to server even when something goes wrong before the experiment successfully completes. That's why you have the data…
-
Hi @Lorraine , You're defining the colors in the run phase of the target_color item. The sketchpad items are prepared in advance, during the prepare phase, and at this time the color variables aren't yet defined. The solution would be to move the c…
-
@elisa But I just want to add a very practical perspective: (...) in the absolute worst case, we’ll end up having to pay an extra couple of participants. I don’t want to suggest we settle for a sloppy solution, but it does seem to me like we’re kil…

Thanks @Fab !
