I can't imagine a scenario where a server without HTTPS does prevent your data from being saved, especially after you successfully run several other components. So, this 500ms timeout is a feature of lab.js. I would need to see the actual source cod…
-
Hi Marko, That is unfortunate. Let's have a look. What do you mean with "its timeout was set to 500 ms"? This isn't one of JATOS' features, is it? It seems to be a component with only a few lines of code: Maybe you could post them here? Be…

There's still the question of why the data for the run the participant did finish were lost even if the participant reached the end of study component. More specifically, I'd like to understand if there's something I can do to moving forward to prev…

Hi Giacomo, I took some time to answer your long question :) Maybe there is a general misunderstanding of how JATOS handles study runs: First you have a study link (e.g. https://example.com/publix/OZTF4BqnlWd), in your case it is of type general mul…

Hi SpacePinguins, better to start a new question. Here it probably get lost. But it might be related to issue https://github.com/JATOS/JATOS/issues/304 and this is solved in JATOS version 3.8.6. Best, Kristian

Nice it worked!
-
I just tried with JATOS on Mindprobe (that has a version of 3.8.5) and I got a confirmation code in the end. https://forum.cogsci.nl/uploads/855/4C2M8P5HPL5U.png Is it, maybe, that you specified a "End Redirect URL" in your study properti…

Dear rvgardt, I'm sorry to hear that you weren't presented with a "page displaying an MTurk confirmation code ... as seemingly promised in the JATOS guide" and "However, have yet to see it". May I first ask which study link type …
-
Hi James, The finishing of the study and sending of result data are often done together but it's not necessary. You can save your data at any time during your study run. And yes, likely your participants closed the the browser tab before the study c…

Do you get any error messages? What's in logs/application.log?

Hi Renato! I always wanted to turn a PsychoPy/Pavlovia experiment into a JATOS one. I'm sure it isn't to difficult - but I've never found the time to do it. Maybe now is the time :) Great idea to put everything in a Google Doc! Now to your question …
-
I agree with Elisa, if you redirect to a page outside of JATOS handling (your lab page), you cannot access any session data anymore (or only with some serious effort). I'd go with Elisa's proposal and add a last component as your lab page. But why w…
-
Hi! It's a know bug in 3.8.1 and it was fixed in 3.8.2. I recommend updating to the latest version which is currently 3.8.5. Best, Kristian
-
Hi! You can use jatos.waitSendDataOverlayConfigfor this. Best, Kristian
-
Hi Elena, experiments running on JATOS are shown to the participants in a browser. Users of browsers can download pictures with a right click and something like "save image". Participants can download and have access to the pictures. Best,…
-
Hi, great you found a way. I just want to add that when you export your result data from JATOS (one of the result pages) and use the "JATOS Results Archive" (the fist one in the dropdown list if you press on "Export Results"), th…
-
There is no limit in JATOS for the number of participants with the General Multiple link.
-
Hi! 1) JATOS itself does not limit the download of files (for whatever file type, e.g. audio, video). But limitations arise from other sources, mostly, the resources of the host machine where JATOS is installed, the internet connection of your parti…
-
Hi Mrockster, Since this seems to be more an issue with lab.js you can also ask in their forum. Best, Kristian
-
Hi Leo, This function jatos.urlQueryParameters should work in all JATOS components of the same JATOS study. E.g. if your URL parameter is called foobar you can access it in any component of this study with jatos.urlQueryParameters.foobar. But maybe …

Let us continue on GitHub issues: https://github.com/JATOS/JATOS/issues/298.

Hi Stephen! Which JATOS version do you use? There were problems like yours in older version that we (thought to have) solved. And actually there are differences in the browsers in regarding file download handling, especially between Firefox and Webk…
-
Hi Leo, Let me chime in here. It seems you are using the wrong version of Java. JATOS still needs 11 or 8. If unsure install the bundled version, JATOS with Java. Best Kristian
-
Hi! I'm too not sure why this happens with your study, but somehow it looks more like an issue with lab.js since you are able to access jatos.urlQueryParameters.Jatos_ID from the browser's console. Maybe your question is better asked in lab.js forum…
-
Hi! Nice you like JATOS (and its documentation) :) First I want to say, that it would have been better to open a new thread in this forum, since your issue is only remotely related to the current one. This way other people can easier navigate the f…

When I say I switched to a LAMP server, this is a default stack for setting up the server for general web use. I don't use PHP or MySQL for JATOS, they are just available on the server if needed. But if you don't use them then the LAMP stack is not …
-
previously I used a docker container Maybe you limited the memory consumption with the docker container then? When I upgraded to the new version of JATOS, I wanted to use a standard LAMP server. I'm confused, LAMP stands for Linux, Apache, MySQL, an…
-
I agree with Sebastiaan. For most usecases it is safe to "just" secure the server and not encrypt the database's data. Actually I've never encountered an encrypted database so far (although I'm not an admin). Best K.
-
Hi! Apparently this 'oom-kill' stands for "out of memory" and Linux decided to kill JATOS because the machine run out of memory. This line 10: 18571 Killed... is just the line of the loader.sh where JATOS gets started. Now the question see…

No, if you have terminal access to the server you can read everything in the H2 database. Use a MySQL or MariaDB for encrypted content. Best, K.
