Hi Kian, The updated result pagination changes are currently mixed in together with other stuff that not yet ready for release. But as soon as I extracted the result pagination changes I'll prepare a release and let you know. But the current Corona …

Hi! I agree with Elisa and just want to answer concretely to your questions if the participant responses are stored in cookies: the participant's responses (in JATOS they are called result data) are stored in a database on the JATOS server. They can…

Hi Maryam, I see you already solved the problem by moving to a different computer. Anyway the first 2 error messages indicate that the problem is on the 'client side' and that it has nothing to do with JATOS. I can see in the earlier posts that Elis…

Hi Maryam, In order to help you we'd need more information about the problem: What is the error message your participants get? If you open your browser's developers tool console do you see more error messages? Does the problem happens only in certai…

Hi Kian, Sorry for the late reply - some holidays came in the way. For a study that we have with 871 participants, the data size we are getting from the table ComponentResult is only 522 MB (we are only using the ComponentResult because this is wher…
-
I'm sorry to hear you had to download your data directly from the database. This is annoying and JATOS is intended to make this unnecessary. May I ask how big your result dataset is expected to be altogether? I'm asking because there is an addition…

It's mysterious :). I'm looking forward to any news.
-
Hm. Strange, from what you describe, ' they could start the study and complete all the elements and the error appeared at the end only (bad request), after they tried to submit their data (after around 45 min)', the only error matching this behavior…
-
Ah, I guess on your local computer where it worked fine you have Windows which is case insensitive when it comes to paths. And on your remote JATOS server you probably have some kind of Linux which is case sensitive and didn't accept your path. Nice…

Hi Jonah! This issue is about browser-side and therefore belongs in the OSWeb forum. JATOS manages the server side. I moved it into OSWeb. Hope you find a solution! Best, Kristian

Hi Yvonne! Great you managed to get the logs. And great you put the way you did it here so others can profit from it. I had a look at your logs. Lets start with the easy things: There is no indication that your server had problems. E.g. there are no…

Hi Kian, I've seen this before. I guess it has to do with your MySQL database setup. By default it limits the amount of data that can be loaded at once. JATOS' docs has a chapter about it: http://www.jatos.org/JATOS-with-MySQL.html#optional-increase…

Hi! It looks like you have a problem with your paths. Can you send me your study and I'll have a look?. If you don't want to post it to everyone here just send it to me personally. But you can't attach the jzip file here in this forum - you have to …

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…
