Hi, I see in the screenshot from @maj_zmaj a line that does not belong there: "Access is denied." But now my knowledge of Windows gets blurry (I work with Ubuntu or MacOS) and added to the non-meaningful error message, I can only take som…

Hi! It's not clear to me whether you want to load those wav files into your experiment or upload them from your experiment to the JATOS server? If it's the latter one, there is an example study 'Video Recording' that does this (https://github.com/JA…

Hi Chloé, you can always program it yourself without using OSWeb. There is an JATOS example study that does webcam and audio recording: https://github.com/JATOS/JATOS_examples/raw/master/examples/video_recording.jzip. jsPsych is working on it: htt…

Hi, I've never seen encryption with an IP address only although theoretically it's possible (https://stackoverflow.com/questions/1095780/are-ssl-certificates-bound-to-the-servers-ip-address). Since you want to use it in your browser, you need one o…

Surprisingly 'Perceptual Metacognition' and 'Invaders with Phaser' examples run fine! This gets weirder and weirder! Just to sum it up for me: your study: not work 'Attentional Capture' (OSWeb): not work 'Go-/No-Go' (jsPsych): not work 'Perceptual …

Hi! Could you please try to install JATOS bundled with Java already (https://github.com/JATOS/JATOS/releases/download/v3.5.2/jatos_win_java.zip). With this we can rule out if there are any problems with your Java. Btw. the bundled Java will be local…
-
Hi Lenny, Hm. You said it runs on cortex.jatos.org, so your study's zip must contain the files (incl images) somewhere. Seeing your errors I somehow assume OSWeb doesn't get to the part where it loads the images because it's not properly loaded its…
-
Hi Lenny, I like that your professor set up your JATOS server with Linux - not many professors would do this (or can do this) :D . I have 2 questions: What does the JATOS test page say (my-jatos-domain/jatos/test)? Everythink OK there? When you run …

Hi, Since Mousetrap is a OpenSesame extension you are more likely to get an answer in their forum. Best, Kristian
-
Nice! (I have no idea why the trail data are logged twice. Weird.) Good luck with your experiments, Kristian
-
You probably mean JavaScript - not Java. They are different languages. And sorry, cant' help, I don't know Python (only Java and JavaScript).
-
2 CPU and 4 GB of RAM should be enough (of course, it always depends on many factors like the files sizes your study downloads, the result data size your study uploads, how many participants work in parallel etc. - but JATOS with 1GB usually works f…
-
Hi Simon, I tested it and it seems to speed up the process of sending the data a bit, but the biggest speed up improvement was when I manually determined the variables to be logged, reducing the size of the data file to 200Ko instead of 2Mo. Weird. …
-
Hi Jasper, I'm actually curious. Where you able to pin point the error? Kristian
-
Hi Simon, I tried your study on my JATOS server and on my local one. I think I know the reason for the delays in the end of your study (I'm not 100% sure though). I think it is a combination of your big result data and the fact that those data are …
-
Hi stpier43, It would be better you open a new thread next time. Although yours is the same general topic the actual problem is most likely a different one. Anyway, so you are using AWS, JATOS v3.5.2 and no proxy. Two things I can think of 1) You sa…

Hi Andrew, What is the file path you are using for your file? Best, Kristian
-
Hi! What does the browser console say? Any errors there?
-
This is a mystery to me too. Maybe it's the browser? I'm using Chrome. I have no clue.
-
Just tried it out on your server. In short: The Prolific redirect seem to have worked with me but I've got OSWeb errors. The good news: I've got redirected to Prolific in the end. https://forum.cogsci.nl/uploads/403/8XR65FJG1VOT.png And the bad news…
-
Hi Simon, I'm sad to hear that your experiment did work out as planned. Hopefully it will get better and you will find a way to fix this. Let me divide your message and answer one by one. Nearly half are participants who tried to start the experimen…
-
Weird, indeed. What irritates me is this error msg you keep getting: "Errors occurred during the experiment". Although it is displayed by JATOS, it originates in OSWeb. Apart from being extremely non-specific, it still hints to some errors…
-
Okay, I checked the URL redirect with your study and it worked here too. I used the cortex.jatos.org server. I did nothing special: 1) I added Prolific redirect URL in the properties of your study. 2) Run your study with the Preview button from Prol…
-
Hi Simon, I think your changes work only if you have only one 'trial' in your OSWeb experiment. As far as I understand OSWeb it does divide your experiment in trails and after each trial it sends the result data back to the JATOS server by calling t…
-
Hi Simon, I'm not sure I understand correctly what you changed in the OSWeb's jatos.js file. But the altered version I linked in the prior post had more changes than just jatos.startNextComponent option to jatos.appendResultData. You can compare old…
-
I've got the files. I also figured out the mystery of why I didn't get notification emails anymore: some of them got into my spam folder. Weirdly only some got into spam while others were delivered properly. I'll try it out at come back here.
-
That is always a possibility. Your laptop has more memory. JATOS embedded database stores everything in the folder /database. So copying this folder (along with /study_assets_root and maybe /result_uploads if you have file uploads) to a different JA…
-
Impressive ;)

Hi Jasper, I wrote the same answer in a different thread. I just copy it here: It's seems as if I don't get notifications for answers in threads at the moment. I stumbled over your answered coincidentally ;). I'll try to monitor this thread from now…

Hi guys, it's seems as if I don't get notifications for answers in threads at the moment. I stumbled over your answered coincidentally ;). I'll try to monitor this thread from now on. You suggested waiting after each trial for a few seconds. Did yo…
