URL of experiment:
Description of the problem: I am trying to display a rectangle (polygon stimuli), which changes color every repeats. The color parameter is feeded from the condition file.
The setup of polygon is below:
My condition file looks like this, which the second column is the parameter for the color of the rectangle.
I kept getting the error below.
I have searched the solution for a while. And I tried to change the column “htbackground” into tuple (eg. (0.804,-0.239,-0.992), or add a “$” for the column “htbackground” (eg. $[0.804,-0.239,-0.992]). Unfortuntely none of them worked.
Any insights helps! Thanks in advance!
