Hi Trig, The quick answer is that it’s all possible, but I wouldn’t (necessarily) recommend it. Within your script you can implement whatever you want. To modify the batch session data you’re most likely going to need jatos.batchSession.add. There’s…

Hi Tony, my first thought would be that the image takes some time to load, and when you test it locally you don’t see this delay because you don’t need to transfer anything though the internet. Two questions: where are your image files located? i t…

Hi Juliet, Kristian will correct me if I'm wrong but your IT should do the update on the server - the problem is when you log on to the server so updating locally on your computer will not help. To update locally, the best is to log in as admin (t…

Hi, Your institution's JATOS is out of our control, and if it worked before we have no way of troubleshooting ourselves. But if your IT say that they didn't get any problems reported by anybody else, then it sounds like the problem is on your side? …

Hi, Sorry for the delay, for some reason we did not get notified of your post. Did you solve it in the meantime? If you didn't, could you please check which is the command that you have on the on_finish callback? (I think that's how it's called). …

Hi Silvia, That's odd. JATOS does not change the appearance of your task. I'll ask a few questions to try to understand what went wrong. You're still running your study locally, right? Do the figures align in the same way regardless of the size o…

Hi Anne, it's hard to tell, my first thought is that the link got cut off in the email, or something along those lines. Maybe ask them to copy and send you back the exact link they're using to access the study? Best Elisa
-
Then you should contact the IT from your university. Jatos is just the software that the server runs, we have no information or control over your specific server. Good luck! Elisa

Hi, we need a bit more information: which JATOS are you using? Mindprobe? Your own server? Your institute’s server? Best Elisa

Hi Pinar, This is most likely an OSWeb issue. If they can't solve it, they'll let us know. You can delete this thread :) Best Elisa
-
Hi Sophie, It's a bit unclear to me what exactly you want to dissociate and at which point. You could in principle provide a 'General Multiple' link and have people complete the task without any link ever made to their IDs. But I suspect you do nee…
-
Hi Jana, If I understood correctly, it sounds like you have separate OSWeb studies and you would like to combine them into one single JATOS study that spans over different components. That's fine. I'll try to go step-by-step Make sure you have a lo…
-
We're working on making a good example for counterbalancing on JATOS (independently from OSWeb). But it looks like you're looking for an OSWeb-specific example, so I'll move your question to their forum. Burt just ask again if you don't get the answ…

Ah, good point, I missed the odd/even idea.

Hi Bo, Your solution to randomily assign roles is as valid as mine, as far as I can tell. As long as you don't have any systematic differences in sign-up order (e.g. women start always first, younger people start always first, etc) then it should wo…
-
Hi Bo, On which basis would you like to assign participants in the group different roles? If you wanted to assign them by order of appearance, it's easy: You could have a first component in your study (or use the waiting room in our examples) where…
-
Hi, yes, the batch should behave exactly in the same way locally as in the server. You've got a typo though: it's jatos.onLoad , not .onload . Maybe this already explains why your code chunk doesn't run? Best
-
Hi zohar, First, you posted this question twice. I'll respond here but please try to keep the forum clean. Second, it looks like you have a file permission issue. That's independent from JATOS. Third, most importantly: Do you want to install JATOS…
-
Hi again, one thing I just noticed: jatos.submitResultData will replace (overwrite) any existing data on the component. You probably should be using jatos.appendResultData instead.
-
Hi Elise, I'm a little bit lost in your code because I don't see where you use the ra_num value in component B. I'll respond to a few different points, they won't be a fully worked out solution but I think it will help you get closer at least. Fi…
-
Hi, There's no built-in functionality but in your case it seems like it will be rather straightforward. You're right that the batch session is the way to go, because it's a data structure that outlives any study run. And given that your participa…
-
Hi, exactly. the test server is not meant for data collection. And your local JATOS is local. You could expose your local JATOS running on your laptop (you’ll find details in the wiki) but the best is that you check out Mindprobe: https://mindprobe…
-
Sorry, there is no way. If you are using a local server of your university/institute, you might be able to talk to your admin and ask if they've set up daily backups. Otherwise, deleted data are deleted. Sorry! Elisa
-
Hi Alberto, Image 2 is odd actually. You do have data, but very weird. I don't see in which case you would have gotten just an opening (or even weirder) just a closing bracket. That actually sounds like a client side (OSWeb/JS) issue. I'll tag @lva…
-
Hi alberto That’s weird: you can’t download any of the result data that are not finished? Are you sure this is the case? I have the feeling you might not have seen a couple of functions in the result table: You can expand on a result by clicking on …
-
Hi Alberto, Ok, in your first message it wasn't clear but it sounds like you are using JATOS on the Mindprobe server. That changes things: Kristian is the official admin but sadly we don't have the capacity to look at individual cases. (If this is …
-
This sounds like a client-side issue. If you write your study using OSweb, you should try their forum. I’ve moved the discussion there.

Hi, On Prolific it's actually easy: use the Prolific ID to align the data from two participants. (See point 2. in this page on the JATOS docs: https://www.jatos.org/Use-Prolific.html#2-optional-consider-passing-prolific-url-parameters-to-your-study…

Hi Kim, we’d need a bit more information to understand the problem. Can you open the console in the browser (on chrome it’s called developer tools) and check which error messages you get, if any? elisa

Thanks, but I wanted to see something more complex than the hello world example, or the default shiny app when one creates a project. This will let me see how a proper survey with many questions looks like and I will know better where to include all…
