Hi mattm. You can always run OpenSesame from source. You can install it either with pip or using anaconda. See https://osdoc.cogsci.nl/3.2/download/#all-platforms-pip For more info on this. If you have an Anaconda or Miniconda distribution running,…

Hi phoenix, This is generally difficult as the mouse cursor is often hardware rendered. It used to be possible when OpenSesame used software mouse cursors, but since it switched to hardware-rendered cursors, I don't really know a quick answer to thi…

Hi Jon, I think correct_response is not allowed to be none. There is likely a check if the value you enter for correct response can be mapped to a key on the keyboard or to a button on the mouse. Alternatively, these errors are often related to pla…

Hi @lmelvill I know that hardware acceleration of Chrome (not Chromium!) on Linux is not working, so it may be that your participants tried to run the experiment in that browser. Alternatively, they use an older version of Chrome (or any browser) t…

Hi guys @kri is right. I've been frequently facing this problem myself. This has to do with the way that OpenSesame interfaces with Jatos. It's high on my priority list and once have the opportunity to work on osweb again, this is one of the first …

Hi @const Thanks for your willingness to contribute. Currently there is no dev documentation for osweb, and you are right by saying the current code base is quite convoluted and in dire need of improvement. We did not start this project ourselves b…

Hi Laura, We would need a little more information to help you with this, as your description of the problem is quite succinct and generic. What are you trying to achieve exactly? Could you formulate it in a more stepwise fashion, supported with some…

Hi Paul. You can implement your own pause() function (that is executed after pressing ESC) if you like. See https://forum.cogsci.nl/discussion/comment/16798/#Comment_16798 Good luck!

Hi Kyrie, This is very difficult to do and sadly not possible in OpenSesame, sorry. This would require fundamental changes to the way OpenSesame currently works yet (e.g. regarding its render and event loop), which we are not ready to work on yet. I…

Hi, Just to be sure, wouldn't you want to place the keyboard_response item after the target sketchpad? I assume you want to collect responses to the target when it is shown and not before that. Regarding the logger item: it does take a few ms to wri…
-
Hi Adam, There is also a repeat_cycle item in OpenSesame. Would that offer an easy solution? In this case, you have to place the `repeat_cycle` item in TrainListSeq below (or after) TrainListLoop. You can then specify in the condition field in repe…

Hi Ram. Yes it is, check out the documentation on coroutines: https://osdoc.cogsci.nl/3.2/manual/structure/coroutines/

Hi Paul, do you mean the music from the last trial keeps playing while the next one starts? Or do you manage to end it correctly (like you state). I don't understand the question maybe, or how the sound becomes scrambled (except for multiple samples…
-
Hi Brett, That is pretty specific, and hard for us to diagnose without having the mentioned devices at our disposal. Have you tried creating a simple python script outside of OpenSesame to see if you can establish a basic connection to PyCorder? Tha…

Hi @phidget , Can you try to see if parentheses around your arithmetic have an effect? So change while clock.time() - t0 < max_rt: to while (clock.time() - t0) < max_rt: my hunch is that this is a precedence issue, as the < and > op…
-
Hi @wilde When I'm putting in my sound files in the "new sample" section, do I have to do a new sample for every single sound file I have? No you don't. You can use variables specified in a loop item, in which case you place a variable na…

Hi Ram_92. You can use the run_if functionalities for this. See https://osdoc.cogsci.nl/3.2/manual/structure/sequence/ and https://osdoc.cogsci.nl/3.2/manual/prepare-run/#conditional-statements-run-if-and-show-if
-
Hi @fotisfotiadis This is because you have placed your code in the prepare phase, while response related code belongs in the run phase. Your code is now executed during the preparation stage of the trial, and thus before a response has even been col…
-
Hi Johanna I do not want to adjust and resize every single image in the files. Unfortunately though, that is the only easy solution. The other one is just as labor intensive, namely setting a scale value for each item within OpenSesame. There are a…
-
Hi KOST, You are describing a basic Go No-go task if I am correct. I would set the duration of the sampler to 0 (or 'sound') and then immediately follow it with a keyboard_response item. Here you can set the timeout to a value in ms for the time tha…
-
Hi there. With facial recognition, you mean facial expression identification, or really identifying faces? Both topics are really hard to cover if you are just starting with OpenSesame, but I'll give you some leads anyway. You can check out https:/…
-
Hi Jose, There is some documentation on how to make OpenSesame communicate with EEG devices, although I don't know how relevant it is to your case. This tends to differ (vastly) between different EEG vendors. In any case, please check out of these d…

Hi Andreea, Have you tried to place these items together in one sequence: A scenario The multiple choice questions belonging to this scenario If you place this sequence in a loop, each repetition should consists of the display of a scenario first, i…

Hi @vatsal454 The Android package is deprecated and no longer support. Most likely the errors you are encountering are due to a lack of Unicode support which is required to display Hindi characters. We are putting all our spare efforts into the dev…

Hi Sina, To help you with that, I can only point you to the https://www.psychopy.org/api/visual/gratingstim.html#psychopy.visual.GratingStim where I would start looking if I were to implement a problem like you describe. I have never created a stimu…

Hi Alex, your question is extremely hard to follow. Could you please elaborate in a more stepwise fashion of what steps cause these problems, because currently I have no idea what's going on or how to help you.
-
Hi @jennab In these cases it's best to just start and learn by trial and error, and at the same time look for someone in your department that does have more experience with OpenSesame (or creating experiments in general) that may be able to help yo…

If you have downloaded and use the OS application, then you are internally using Python 2 (which is packaged with OS). To be honest, I've more often seen the message "Python seems to have crashed. This should not happen. If Python crashes often…

Hi Bronagh, I must say that I have grossly neglected maintaining the media_player_mpy and underlying python-mediadecoder packages. There are some other open issues at https://github.com/dschreij/mediadecoder that are still on my radar, and I will ad…

Apparently I forgot to include openpyxl as a depency while packaging OS for Mac. I've added it to the list and will try to perform a new build soon.
