Initially, participants are asked to enter their participant’s ID in the box as soon as the experiment is launched. But how can I assign ID automatically in the beginning of the experiment? Can I ad a line of code which generates and ID in Experiment info?

On Windows in Windows Explorer you can go to Options → Change folder and search options → View → Show hidden files, folders and drives. The local .git folder is hidden by default and contains the information about the connection to the project online.

I’m on Mac and found how to show hidden files. I deleted the .git folder and synced and made a new project, but still no .js file created. I added you to the new project too (face_exp_hadhelp).

I downloaded your project and pressed the sync button and now you have a JS file.

Hello, Thank you so much for that, I can now see there is a js file! I ran the experiment online using http://moryscarter.com/vespr/pavlovia.php?folder=lydiabrown&experiment=face_exp_hadhelp/ and it almost worked. The experiment actually started and ran which is a great step, but the counterbalanci…

Hi @wakecarter , I think it’s still the same problem that I can’t make changes and update the js file…? I made a little change to the text just to see if I could update it and as shown below it updates the .psyexp file but not the js files. [Screenshot 2021-04-13 at 11.27.27 am]

Just checked, export html is set to “on sync”. I then went file > export html and synced, but it still hasn’t updated the .js file. When I clicked export html if gave this error message: Generating PsychoJS script… Traceback (most recent call last): File “/Applications/PsychoPy3.app/Contents/Res…

Where do you define group? BTW, on the original subject of this thread I now have a new web app which assigns new IDs to each participant with additional bells and whistles. [image] New web app. VESPR Study Portal Online experiments https://moryscarter.com/vespr/portal/ …

Dear @wakecarter , stumbled upon your webapp and found what i was searching for - thank you so much! I’ve had a few testruns with my custom experiment link and it works like a charm. However, now that i want to start collecting new data from scratch, is there a way to start incrementing participan…

Hi Elias, Since resetting the participant count requires me to go into the database, but isn’t really necessary (participant numbers can start from any figure) I now ask people to “ buy me a coffee ” if they would like me to reset their counter. Licenced users of my new Study Portal can do this thems…
