David, that is great! Sorry for sounding a bit harsh in the last post. But I'd like to ask you a question: It's a unusual these days to use Windows instead of Linux as a server OS. Why did you choose this? I'm just curious. JATOS works on both.
-
I agree with Daniel. Move the timeline definition inside the jatos.onLoad and it should work. You can use the jatos.studyJsonInput only after jatos.js' onLoad event is fired and to wait for this one must use the jatos.onLoad function.

Hi everyone, the pictures/screenshots are lost here due to a server crash and corrupt recent backups of this forum. Can you upload them again?
-
JATOS is its own server. IIS is just Windows' standard web server. In the Linux world IIS is comparable with Apache. But from your question I deduct that you are new in this administration world. Is there maybe an IT department/guy that can help you…
-
I'm by no means an expert in Windows administration, but I think in what you said, 'since I assume it is clashing with IIS', you were probably right. IIS is bound to port 80 and JATOS can't bind to it anymore. JATOS does not need IIS - it runs indep…

I just wanted a proof of concept. I used the example from https://github.com/muaz-khan/RecordRTC and adapted it for jatos.js. It's in the JATOS Example Studies: "Video Recording - Record a video with the webcam and upload the data as a file to …
-
Update: I tried a video recording and uploading of 2 min (17 MB file size) on Chrome and it worked nicely. Update 2nd: With video recording of 5 min I had problems: got only HTTP status 400, 'File size too large'.
-
@Daniel I understand. I'm curious because JATOS since one of the last releases has the possibility to upload files (similar to result data - but whole files) and what I got so far most researchers want to use this feature to record audio or video. I…
-
@Daniel I'm just curious why do you think sound recordings in the browser are difficult? What are the security restrictions? Isn't it just a popup from the browser asking the participants if they allow it?
-
Hi @penguin , as Daniel said, you can use JATOS' study session to share data between components of the same study. You'd have to set the data in the one component and then in all later component you can access them. Another way would be to use the J…

Hi Vatsal, Do you see any errors in your browser's developer tools? And I can't run your experiment. I get: The batch (ID: 6) is inactive. Best, Kristian
-
So I tried it on my JATOS and it seemed to work as expected. I set the Max total workers in Batch Properties and tried to run the study with General Multiple Worker and to be sure with Personal Single too. I could run the study as many times as I sp…
-
That is good to see! But this leaves the questions for me why it was so weird with JATOS' Max total workers in Batch Properties. Let me try this out on my JATOS.
-
Hi Tobias, yes, I miss messages here too although I'm subscribed. Sometimes I just don't get the email. Luckily this happens seldom. Release will come out in a couple days. We are still testing. There are a couple other jatos.js changes and changes …
-
Hi Mark, Where in JATOS did you set the 'maximum number of 8 links'? Is it the 'Max total workers' in 'Batch Properties'? And what was the error message your participants got? I'm asking because I want to figure out if this is a problem on JATOS' or…
-
Okay, I will do.
-
Hi, Interesting. Do you want this out of privacy reasons? JATOS right now stores the start and end date (a Unix timestamp) for each component run by a participant. The same it does for the whole study. From start and end date it calculates the durat…
-
It actually helped :). Just not the on_load but the on_trial_start callback function. But this is not the only thing - I had to change jatos.js a bit this will only be part of the next release 3.5.5. (should come out in a couple days). The problem w…
-
Hi dror, Looks like you installed JATOS in a folder 'jatos' within your user's home folder. Since your user is called 'ubuntu' I guess the path to your JATOS folder is '/home/ubuntu/jatos'. But you can check that by typing 'pwd' while being in your …
-
Hi Tobias, You seem to be right. I just tried the jatos.addAbortButton with jsPsych and it was not added. Somehow jsPsych seems to prevent adding of new elements to the DOM. Weird. I have to have a closer look at this. Best, Kristian
-
Hi! This line of your logging seems to explain your problem: Jun 07 21:53:42 ip-172-31-17-88 systemd[7213]: jatos.service: Failed at step EXEC spawning /jatos/loader.sh: No such file or directory Somehow the path to the loader.sh seems to be wrong. …
-
Hi Dror, Try without the line ExecRestart=/bin/kill $MAINPID - apparently it's not supported by systemd anymore and also not necessary. And if this doesn't help we'd need more information: What did you try so far? What is the error msg? What is your…
-
Hi, You can basically put this jatos.addAbortButton() anywhere where code is executed. So right next to where you call jatos.onLoad should do fine. jatos.addAbortButton(); jatos.onLoad(function() { jsPsych.init( { // ... }); }); Best, Kri…
-
Hi, I don't know what causes your problem that the second component doesn't start for some people, but I think your warning has nothing to do with it. This warning is just about that Chrome can't load the SourceMap for your JavaScript file (https://…
-
Nice! :D

Hi Ivan, If I want to use AWS I have to install JATOS on my local machine so I could add the path to it according to the tutorial on the site you proceeded I don't understand this part. You don't need to install JATOS on your local computer in order…
-
Hi Ivan, I think I understand: you close the terminal to your remote server (on AWS) and in this terminal you started JATOS, right? If you close a terminal all processes (including the JATOS one) are terminated. You need some kind of auto-start like…
