Hi Gérard, Could you upload one of the clicky samples here? Cheers! Sebastiaan

Hi Leo, This is a good point, and it results from the (poor) decision long ago to use the strings 'yes' and 'no' for True and False in OpenSesame. (And changing this is tricky because of backwards compatibility.) Since all non-empty strings evalua…

Hi Yuval, This is a known issue with bounding boxes around text leading to sometimes unpredictable positioning. A workaround for that is described here: https://osdoc.cogsci.nl/3.2/manual/stimuli/text/#vertical-alignment This should be fixed in Open…

Hi Alessio, I believe that this is a general problem with PyGame not flushing key-press events on Ubuntu. I'm not familiar with any workaround for this. But if you select the psycho backend (with PsychoPy), the issue should probably not exist. Is th…

Hi Dsyfaro, You need to run OpenSesame as administrator so that it can write to the program folder. For more information, see: https://osdoc.cogsci.nl/3.2/manual/environment/ Cheers! Sebastiaan

Hi Florian, There is not much you can do about the mouse cursor being reset to the center upon you're showing/ hiding it, except changing the backend settings until you've found a combination that doesn't suffer from this. (It's difficult to provide…

Hi, You'll have to be more specific! How exactly have you tried to install OpenCV, and what kind of error do you get exactly? You first need to have installed OpenCV before you can use this to render videos! But here's an example of how to use OpenC…

Good to hear! (PS. This alignment issue will be fixed in the next release of OpenSesame.)

Hi Anton, If I understand correctly, you want to check the loop table for whether any of the values under Responses matches any of the values under words_var . And if so, you want to use values from alternative_word_stimuli instead of word_stimu…

Hi, It's tricky to combine presentation of video and a static Canvas image. It's possible but would require substantial scripting, for example with OpenCV: https://www.learnopencv.com/read-write-and-display-a-video-using-opencv-cpp-python/ So perha…
-
Hi Sophie, I'm not sure to be honest. To start, maybe you can present several different minus-like characters in a single string. Do they also appear identical then? If yes, then I suspect that the font simply doesn't contain these variations and fa…

Hi Mollie, The problem is that 'object_2' is a key in the stim_match_1 dict. I updated the code above to show how you can add it (marked 'update'). Cheers! Sebastiaan
-
Any advice? Yes, to post the actual error message ?

Hi Laura, When entering the code, I need the backspace to delete the last letter written (like in a Word document). But, when I upload the experiment and I press backspace when entering the code, it jumps to the website that was opened before I star…

Hi Laura, That's a bug that's fixed in the latest version of OSWeb. If you upgrade opensesame-extension-osweb , this problem should go away. https://osdoc.cogsci.nl/3.2/manual/environment/ Cheers! Sebastiaan

Hi Zhenzhen, There's nothing wrong in your experiment, as far as I can see, that would unnecessarily slow things down. And for me it works fine. This suggests that there is an unfortunate interaction between the video card of the lab computer and Op…

Hi Boris, The JATOS server at the RUG is managed by the instrumentatiedienst of the Faculty of Behavioral and Social Sciences. Cheers! Sebastiaan

Hi Jessica, With the regular desktop application this is not possible, but opensesamerun allows you to specify the subject number and log file on the command line, like so: opensesamerun my_experiment.osexp -s 0 -l logfile.tsv Cheers! Sebastiaan

Indeed, we are having some forum troubles and some attachments got lost. But it should downloadable again now through the link above!
-
Hi Zhenzhen, It would be easiest if you upload the experiment here so we can see what might cause the delay. It's probably in part due to the interaction between the hardware and OpenSesame, but even so there might be ways to optimize it. (I think s…
-
Hi Mollie, If I understand the logic correctly, then would simply change this line: targets_with_repetitions.append('object_1') To this: targets_with_repetitions.append(choice(['object_1', 'object_2'])) Cheers! Sebastiaan
-
It should be downloadable again! (We've been having some issues with the forum lately, and some attachments got lost.)

Hi Gérard, Could it be that some Python or other underlying files would not have been deleted when I have uninstalled and reinstalled the OS package ? No, that strikes me as very unlikely. But what it could be I don't know … As you say, it sounds l…

@Yavor Can you chip in here?
-
Congratulations!
-
All the different software versions are a bit confusing, I understand that! ;-) but OpenSesame 3.2.8 can run with Python 2 or 3. So the versions of OpenSesame and Python are independent of each other. Also, OpenSesame comes with its own Python inte…

For some reason some attachments got lost in a recent update to the forum. But here it is again, an improved version of multiple-character input for OSWeb! https://forum.cogsci.nl/uploads/622/LV2SE8AZL5Q0.osexp

Hi Gérard, If you only hear a click when playing sound files, this generally indicates that the format of the sound file is different from what OpenSesame expects. (Although I'm not sure why this would happen on some systems and not others.) Unlike …
-
Hi, Thanks for reporting this. We're aware that this happens sometimes, and it's pretty awful when it does. It's always due to a bug somewhere in the underlying libraries, and therefore really difficult to debug. As a workaround, you could try a dif…
