I am using Psychopy Builder.
I have several condition files. ‘Condition_file_1’ , ‘Condition_file_2’, ‘Condition_file_3’ and ‘Condition_file_4’ [all of them have experiment trials,they are simply different counter balanced conditions]. They have 24 rows each. I wanted to select one of these condition files up front.
I found information from this page very useful https://groups.google.com/forum/#!msg/psychopy-users/GMP6hF2ACuQ/dqwIrPw0DwAJ and achieved this by using $expInfo[‘blockFile’].
I also have another condition file called ‘Condition_file_Filler’ [has filler trials]. It has 12 rows. Both the experimental and filler files have same column titles, thus simply interchangeable.
The inner loop at the moment has ‘Condition_file_1’ and the outer loop has ‘Condition_file_Filler’. By default, psychopy starts to play the rows in the innerloop followed by outerloop.
What I want ?
I want one row (order can be random or sequential, it doesn’t matter) from ‘Condition_file_Filler’ to be presented after every two rows from ‘Condition_file_1’.
Any suggestion about how to achieve this?
