Hi Jelle! My first guess is that you university's JATOS server is out of disk space. Can you contact your admins and ask them this? Best, Kristian

Hi Chris! Strange it works with me. I just tried. And I didn't change anything there. Can you try with another browser and/or delete the cookies for https://experiments.jatos.org/ in your browser? Best, Kristian

It seems like you expect your study to be used by others and you try to anticipate where they would set input parameters. Usually people program a study for themselves or their team and don't try to make it fool-proof - they just try to get it to wo…

Hi Craig! Nice to hear you like JATOS. And thank you for your feedback and feature wishes. We really need this type of feedback to learn what people need in JATOS. Now to your main wish: exporting meta data. JATOS does have the possibility to export…

Hi Vlada, About the error you have: "A worker with ID 4741 doesn't exist.". Did you activate General Single Workers in the Batch in which you are running your study? By default they are deactivated. Best, Kristian

Hi Felix! Let me answer your 2 questions: but what I'm not clear on is how to link to jatos.js via relative path jatos.js get a special treatment in JATOS since its JATOS' own library. The relative path that works since 3.3.1 is: <script src=&quo…

Hi Yvonne, You got already somewhere :). Docker can be confusing. Docker has a cp command to copy files between container and host. Have a look at this SO question: https://stackoverflow.com/questions/22049212/copying-files-from-docker-container-t…

Hi Lea! Hi Felix! The thing with the relative paths is, although they are much handier and less error prone, they are only supported since JATOS 3.3.1. If you use relative paths and import your study into an old JATOS < 3.3.1 then it will not wor…
-
Hi Lea! What type of path do you use in your experiments: relative like "lib/survey.js" or absolute like "/study_assets/my-exp-folder/survey.js". I guess it is the later and then the easiest solution is to switch to a relative pa…

Hi Yvonne, Let me answer one by one: yes, unfortunately, the study is relatively long (45min - 1h) and attempts to replicate the error are therefore quite time consuming. If the study takes that long it's difficult to figure out what went wrong. I s…
-
Hi Yvonne! I'm sorry to hear your study continues to have data loss. It's difficult to say what went wrong if there is no reliable way to replicate this problem. Can you check the JATOS log for errors (or send them to me and I check them)? And I me…

JATOS puts all query parameters into jatos.urlQueryParameters that you can use in your JavaScript. http://www.jatos.org/jatos.js-Reference.html#original-url-query-parameters So if your URL is ".../jatos/publix/56/start?batchId=56&generalMu…

I agree with what Daniel said but just to get an idea: what is the file size of your images?
-
The server was fine at this time. Plenty of resources left. In the log was also nothing unusual: last entry was a jatos.appendResultData. After that nothing. I guess your problem is more of a browser / OpenSesame / OSWeb one.
-
I can only say something for the JATOS side of the issue since I'm not professional in OpenSesame. We thought perhaps it is a memory issue on our JATOS server. It has 2 Gb. We are in the process of upgrading it to 4 Gb. But we tried running our exp…

Hi Jonah, I assume with 'log files' you mean exporting result data and downloading them as files (JATOS also has log files but they have a different purpose). if I am not mistaken, default log file name is the downloading date and time of the compu…
-
Try with this line instead: <script src="jatos.js"></script> And I tried your study and got an error that 'results' is not defined at this location: // Show data (JSON format) var dataAsJsonStr = JSON.stringify(results); And th…
-
That is one solution :) My guess on why it did not work with a simple 'jatos.onLoad' is that the execution of your JavaScript never reached that point in your code. But to confirm I'd have to see your code. Anyway, with using a button you circumvent…
-
Hi Cristina, The code you posted looks fine. Do you get any error message in your browser's Developer Tools? And if you don't want to submit any result data you can just use jatos.startNextComponent directly without calling jatos.submitResultData fi…
-
Version 3.5.6 is fine. It sends the result data in the background and waits until they are all transferred before it finishes the study (so the 20s pause in the end of your experiment shouldn't be necessary). What confuses me is that your study runs…
-
If you are using JATOS you can use the 'End Redirect URL' field in your study's properties to direct participants to a survey link at the end of the experiment: http://www.jatos.org/End-page-after-your-study-finished.html#3-study-properties-end-redi…
-
May I ask which JATOS version you are using? In older versions of JATOS + OSWeb the behavior you described was possible but this was fixed a couple versions ago.
-
Hi Romàn, Do you mean with 'deleted participants' that you deleted the study results (by pressing the red button in the study result page and confirmed the dialog)? Then there is no solution to get back those data - unless you have a backup of your …
-
Hi Laura, Can you tell us a bit more about the failing data transfer? Do you get any error message in the developer tools of Safari? Does it fail always at the same point in the experiment? Does it happen with all participants using Safari or can so…
-
I admit the error message is confusing here. I will change it to something more meaningful that mentions that cookies should be allowed. But the reason that the error msg mentions something specific as the result ID is okay. The JATOS internal flow …
-
Hi! JATOS needs cookies to work (first party cookies only). JATOS uses cookies to pass on information about the study run (e.g. study result ID, batch ID) from the JATOS server to the participant's browser where it is picked up by jatos.js. JATOS do…
-
Hi Roger, About you first question, customization of the max batch workers reached message: unfortunately not, there is no easy way to customize this. It's hard-coded into JATOS without the possibility to configure it. And about the second question…
-
Hi Mireia, It's difficult to say something about your problem when there is no way to reproduce the problem. And I'm reluctant to try the provided link to your study, that takes 25-30 min, if there is a high chance that the problem will not turn up.…
-
Hm. I'm not sure if this is a problem of your experiment, OSWeb, JATOS or a network problem. But maybe with some questions we get somewhere: Is there a way to reproduce the problem so we can have a look at it? Can you give us a JATOS study link or a…

This reminds me of another recent question here: https://forum.cogsci.nl/discussion/6503/export-trial-by-trial-data-from-an-online-osweb-exp-running-in-jatos How do you do your experiments? With OSWeb this might be difficult but if you program it yo…
