  • I had another idea: are you using a MySQL with your JATOS? Then I'd strongly recommend to turn off the binary log (https://www.jatos.org/JATOS-with-MySQL.html#optional-deactivate-mysqls-binary-log). Kristian
  • There is a non-standard character in your result data. In heure normale dÂ’Europe centrale, the char before Europe is not UTF-8. Do you know why it's there? But if you just want to go on, you can replace all dÂ’Europe with d'Europe in an text editor…
  • 10 MB is pretty large for result data (even for OpenSesame ones). I recommend you try one more time to reduce the size. I had a look at your example result file and saw many repeating fields. But to answer your question: No JATOS has no other restr…
  • JATOS exports in utf-8. Strange. Do you have an example of the exported results that I can check. You can attach the file here. Best Kristian
  • Hi Stephan, JATOS' MTurk integration is already quite weak. Most importantly it does not use MTurk's API. What it does is providing some code that can be copy-pasted into MTurk. That code contains a link to your JATOS that when opened starts a study…
  • Yes, I thought the same. Probably link somehow got changed. Kristian
  • Exactly, usually one doesn't encounter STARTED. If the study started the correct state is DATA_RETRIEVED.
  • Your screenshots are from the Study Result page and each row in the table shown is a study result. I guess you did a couple of test runs of your study? Each run results in one study result. If you don't need them you can just remove them. Here is li…
  • Moved to OSWeb forum
  • That is nice! Do you think others could encounter the same problem? Then please consider sharing it here with us.
  • So JATOS started without errors. Hm. Java is not the problem - JATOS would start without it. Is there something blocking access to port 9000 on your computer? Is there maybe some kind of firewall / virus protection installed?
  • Not sure what's going on. What's in JATOS' log. You can find them in the installation folder in logs/application.log and logs/loader.log. Are there any exceptions or errors?
  • Sounds to me like you started several loader.bat. Or some other server is using port 9000. What happens when you open localhost:9000 in your browser?
  • Hi Ethan, Yes, the blog post you mention is quite old and it's on my list to write a new version of it - but my list is pretty long ... And it's difficult to say: there are many factors that come to play, e.g. Number of users and studies Number of p…
  • Hi, from what I see in your folder structure your JATOS started normally. What happens when you open localhost:9000 in your browser? And do you get any error messages in the terminal window that opened after you clicked on loader.bat? Best, Kristian
  • It worked for me on a freshly installed Windows 11. No problems, no errors. But do I understand you correctly, you got it going on your machine? I'm not so much a Windows user anymore. Do you think there is a bug in JATOS running on Windows 11? Is t…
  • Hi, I didn't try JATOS on Windows 11 yet. Let me grab a copy and come back to you. Best, Kristian
  • Exactly this, jatos.js is magically added by JATOS. You never have to add it yourself. Although you can use your own version of jatos.js. But this makes only sense if you have somehow adjusted it. Best Kristian
  • Yes, JATOS works with jsPsych 7. I just turned the 2 example experiments from their tutorial into JATOS studies. You can try them out: https://forum.cogsci.nl/uploads/209/WCDQPK8RTE9W.zip https://forum.cogsci.nl/uploads/716/Z71P1TQLQS2N.zip Best, Kr…
  • Hi Saurabh, Actually the "Import properties" button lets you import the whole component properties (!= study properties) in JSON format and that includs the "JSON Input". It has an easy schema. Here is an example: { "ver…
  • Weird, one would think 7 days is greater than 300 seconds. Maybe there is/was another proxy/gateway that causes the timeouts?
  • That's a shame. JATOS gets updates constantly. Maybe try to talk to your admin again or tell him to talk to me. Updates are less difficult then they seem. And the newer versions have an automatic update that makes it even easier.
  • Hi Julius, if it is just about working together on a study, e.g. being all able to access the result data, you can add your students as members of the study. As members of the study they have the same rights as you have. Just go to your study -> …
  • Looks like your JavaScript objects (trial_data) weren't properly serialized to JSON. Try: jatos.appendResultData(JSON.stringify(trial_data) + ","); Best, Kristian
  • Hi, I see from your screenshots you are using jatos.uploadResultFile. By default JATOS has a limit of 30 MB for file uploads but this can be changed in the production.conf. So file size shouldn't be your problem if your files are max 7-10 MB. But I …
  • jatos.submitResultData() and jatos.appendResultData() are the functions to save data in JATOS' database. There is also jatos.uploadResultFile() if you have larger data like images or audio (https://www.jatos.org/jatos.js-Reference.html#result-data-a…
  • Yes, a newer JATOS version would help here. In v3.5.3 we added the 'httpLoop', that deals with this kind of problems. The current version is v3.6.1. Nice that you could find a solution that works for you. There is no ugly solution if it does the job…
  • You can get the version via jatos.version. Should give you back a string. (I'll answer the rest later)
  • Hi Dorian, actually, which JATOS version do you run on your server? Maybe a newer version can help here already. Best, Kristian
  • Yes you need admin rights for that.
