JATOS doesn't care of the type of data you put in the results or the uploaded files. It can be text, images or in your case video. So yes. But the other question is whether OSWeb supports this and there hopefully others can help @Daniel, @sebastiaan…

I'm not an expert in Traefik, just using it every now and then. But from there documentation (https://doc.traefik.io/traefik/middlewares/buffering/) I'd say it's enough to set maxRequestBodyBytes.

Hi Deiniol, I uploaded your combined study to your OneDrive: the file posLeft.jzip. Please check that everything is correct, e.g. I think I missed to copy your study's comments. Apart from that, I think, it works. The trick was to use the path with …

Hi Felix! I fixed the issue. More about the reason you can find in the Github issue: https://github.com/JATOS/JATOS/issues/208. The new version (v3.5.8) is still in pre-release but I installed it already on cortex.jatos.org for you to try out. I tri…

Hi Yvonne, Sorry for taking so long to answer. Apart from the 'bad request' error you also have an 'EntityStreamException' which can or can not have something to do with the first error. This 'EntityStreamException' just states that the request wasn…
-
You would have to specify this in the instructions, there is no way to configure this in JATOS. And it's better to put this in the early instructions in MTurk that appear before the worker accepts the HIT.

Hi Felix, I checked with Safari and had the same error as you: JATOS isn't allowed to run a study with the study result ID ****. Then I tested it on Chrome and Firefox and it worked. Then I tested with different worker types, Personal Multiple and G…
-
Interesting. It would be strange that Safari somehow alters the URL query parameters. But I'll test it: I do not have a Safari browser at hand right now but I'll test it this evening on another laptop at home and come back to you. Kristian

Hi Yvonne, Someone asked a similar question on Github (https://github.com/JATOS/JATOS/issues/204). I think there we couldn't find the reason for the error due to time constrains. But one possible cause was that somehow the 'srid' parameter in the U…
-
I'm a bit hesitant to give an definite answer. This question is in the OSWeb forum and I don't know much about OpenSesame/OSWeb. But I know about JATOS and from JATOS point of view it is no problem to deliver arbitrary files and in this JATOS is not…

Hi Felix, That is strange indeed. I just tried too, like you said, same email for Worker Sandbox and Requester Sandbox, and it worked fine like before. You can try it too: https://workersandbox.mturk.com/requesters/A3ER60IEU77H9M/projects?ref=w_pl_p…

Hi Felix, I just tried it out with MTurk Sandbox and it worked. Try it yourself: https://workersandbox.mturk.com/?filters%5Bsearch_term%5D=kristian&page_size=20&page_number=1&sort=num_hits_desc&filters%5Bmin_reward%5D=0 I did nothing…

... and to add a user to an experiment you have to do: go to your study's page -> More -> Change Users -> add lange.kristian@gmail.com into the field 'Add user by username'.
-
Ah, sorry, my user is lange.kristian@gmail.com :)
-
Hi Felix, That's strange. Are you running your experiment on experiments.jatos.org? If yes, can you please add me as a user of your study (only if there are no sensitive data already collected)? Then I can have a look and try it out myself with MTur…
-
You better ask this question over in the OSWeb forum. There are the experts.

Hi David, I think I understand what you want to do: The analysis would run on a different host in Python and you would somehow send data via an HTTP request to this host. So the process would look like: trial in OpenSesame -> HTTP request to diff…
-
Are we talking about video playing or video recording? And to answer the second question: JATOS supports file loading and uploading. Those files can be anything including videos.
-
Hi, Nice to hear you love JATOS :) If I understand you problem correctly: you got a server, installed JATOS, start it - and then if you close the SSH terminal JATOS gets terminated too. This sounds like you want to run a program in the background on…
-
Hi CSC, Hi Eduard it's always a bit difficult to arrive in a thread that was going on for a while: I'll try. I think CSC's questions is only loosely related to srossmktg original question. So I'll only answer this one. You seem to have 2 problems: …

Hi Jelle, (1) participants ran the experiment in Safari; I know about issues with audio files, but we only used images in this study; I don't think Safari is the issue (2) they participated in Canada, whereas the JATOS server is hosted in the Nethe…
-
Hi Dror, I think I understand what you want to achieve. In JATOS lingo: you don't want pre-created workers but create them on the fly when the participant clicks on some link. There are three worker types that are created on-the-fly: General Single,…
-
Eli's way might work but I was talking about a subfolder for each component and in each subfolder you will have one OSWeb experiment. In your file system (you can change the naming of 'exp1' and 'exp2': C:\jatos_win_java\study_assets_root\PrimingPr…
-
Then you might have been just lucky. Reliably you can access jatos fields like jatos.urlQueryParameters only after jatos.js in initialized. Usually this is very fast and your code might have worked anyway in most cases but I'd strongly recommend to …
-
I just tried on experiments.jatos.org and there it works. I see yours is on windows. Can you try without the space, just 'part1'?
-
Hi Skilli! You can't change the first part of you path, but you can change everything afterwards including adding subfolders. You could put each of your OSWeb experiments into its own subfolder, e.g. exp1, exp2, .... And each subfolder will have its…
-
This is just one, isn't it? With just one participant I'd say it's like you said: 'they ... did nothing and directly closed it before the call was sent.'.
-
I'd say it's better to ask this question in the OSWeb forum where you will find the experts for this.
-
We moved your questions to the OSWeb thread because it seems to be more of a OpenSesame/OSWeb problem. JATOS just makes all query parameters available through jatos.urlQueryParameters .
