Hi,

I wanted to get rid of the experiment settings dialogue and I disabled it. Now I cannot open it anymore. Same problem as (Can't access experiment settings dialog).

I did read the Python to Javascript crib sheet and now I know I shouldn’t have disabled it, but now I don’t know how to be able to open the experiment settings again.

Any hint?

Thanks!

This is one we’ve fixed for the next bug fix release, but essentially you need to open the .psyexp file in a text editor (Notepad, Sublime Text, etc.) and replace the line:

<Param name="Experiment info" val="{}" valType="code" updates="None"/>

with:

<Param name="Experiment info" val="{'participant': '', 'session': '001'}" valType="code" updates="None"/>

Thank you for your reply. I updated Psychopy and now I’m getting this error:

This worked for me, because I had disabled my dialog box too. Thanks!
