Hi,
you can select a condition file based on a participant number right from within the loop properties and without code component.
For example, we use the following input in the conditions textfield of the loop properties to select an appropriate balancing condition based on the participant number:
$‘playlists/balancierung_’+str(int(expInfo[‘participant’])%4)+’.xlsx’
Just adapt it to your needs.
All the best,
Frank.
