No answer from Mindprobe? They are probably in holidays. Please send me an email (lange.kristian@gmail.com) and I'll create an account for you on Mindprobe. Now for your DO droplet: it's difficult to say from the outside what's going wrong there. Di…

Hi! JATOS exports the result data into a text file where each line is a separate result. So what you have to do is split this file by lines. I'm not familiar with Matlab or R, but I was told that if you read the results with jsonlab (Matlab) or rjso…

Hi Aya, Just playing video and running in batches sounds fine. I wish you all the best with your experiment! Kristian
-
Hi! I need you to answer 2 questions for me in order to decide if your study is to heavy: Do you want to record video and upload it to JATOS or just play video? What's the size of the video file? Roughly, how many participants do you expect? Best Kr…

@sebastiaan Anyway, issue https://github.com/JATOS/JATOS/issues/224 shouldn't be too difficult to implement and it might be nice to have for other things too.
-
Hi Sebastian, jatos.endStudyAndRedirect() shouldn't close the study prematurely but I'm not sure what you mean with 'bypassing the data transfer that happens at the end of the experiment'. But jatos.js ensures that everything you send via jatos.subm…

This issue doesn't really fit into this forum - it's more an admin question. You (or an admin) will have to log in to your server's terminal and figure out what's going on there, check why JATOS isn't working anymore. So you have access to your serv…

Hi Vassilis, It's difficult to say anything about your server from remote. Your error page is the standard one that is shown if the server doesn't answer. Have you tried turning it off and on again? After 2 years running a reset might solve it alrea…

Hi! It seems like something is going wrong with your study: the only state that indicates a successful study run is "FINISHED". You've probably seen the state descriptions already: http://www.jatos.org/Manage-Results.html#table-columns. So…

Hi Vatsal, on DigitalOcean it's quite easy to backup: just do a snapshot of the whole droplet. In your Droplet's menu is a point 'Snapshot'. You can to it 'live', while your server is running or power down and then do the snapshot. The latter one is…

Hi Marit, I assume this has more to do with OSWeb than JATOS and therefore I move this question into the OSWeb forum. Best, Kristian

Hi Vicho, If you get the result data from jspsych after each trial you are responsible by yourself to turn them into proper JSON. JATOS doesn't care for the format - for JATOS they are just text. Each jspsych trial gives you JSON, but if you just us…

I'm sorry about the deleted users and studies. I had the impression that this installation is still in the process of installation. But nice it's working now. Best, Kristian

Strange, all tables there but the one. Maybe the database evolution got confused. Could you please try to set up the database anew: stop JATOS, drop the JATOS database, create it again, start JATOS. And what version is your MySQL? Best, Kristian
-
Can you log into your MySQL, into JATOS' database there and run show tables; for me? What's the output?
-
Hi Juliana! Does your MySQL runs on the same host as JATOS? If so then you can just use 'localhost'. E.g. my database configuration in production.conf looks like: # Database configuration - MySQL database # ~~~~~ db.default.url = "jdbc:mysql://…
-
Hi! Yes, you are right loading of all study results fails because there are too many data. The underlying reason is that JATOS loads (actually not JATOS but a library called Hibernate) all data first into memory and only then sends them off to the b…

Nice you made docs about this. It's a common question. Now we have something that we can just link.
-
Nice you could solve it :). I'll leave it here. You found an answer to your own question - maybe others can profit from it.
-
Hi Sebastiaan, What do you think about this? I think it looks fine. But let's ask @Eli for her opinion, she did several studies with counter balancing. Btw. you can use jatos.batchSession.move to move elements from one array to another: https://foru…

Hi Yavor, At this point I'd recommend to recover your old 3.5.5 from your backup and do a manual update. Although I'm quite curious what's causing the problems, without direct access to the server I can't say much. Best, Kristian
-
I might be mistaken but I think the Same Domain Policy doesn't stop you here, at least not if you are just playing the content (https://stackoverflow.com/a/27431853/1278769).
-
The warnings in your application.log are normal ones, nothing related. What are the warnings in the loader.log? They might be more important. Best Kristian
-
Hi Tim, I can only speak from the JATOS side here. 50k files is a lot and although JATOS could probably handle them given a strong enough server, file serving is not what JATOS is specialised in. JATOS or JavaScript (and I hope OSWeb too) don't care…
-
Hi Guy, There is no environment variable for this parameter yet that you could use for your docker. I made only the common parameters configurable via environment variables. It's not a big thing to add it for this one to but the change would only be…
-
Turning off the X-Frame-Options might help. Add this line to your conf/production.conf and restart your JATOS: play.filters.headers.frameOptions = null Best, Kristian
-
Hi Yavor, I checked your errors again and it's likely not a permission problem - I jumped to a conclusion there. It's more of a problem in JATOS that it can't correctly shutdown (for unknown reasons). Since you can run `systemctl restart` I assume …
-
Interesting: this error states a permission problem: java.lang.IllegalStateException: cannot create children while terminating or terminated Which OS are you on? How do you run JATOS (docker, systemd, proxy)? What are your JATOS users permissions? B…

Hi Yavor! My updates worked so far. What do JATOS' logs say? In the log folder are several log files, application.log, update.log, loader.log. Are there any errors regarding the update? Best Kristian
