Hello,

I'm wondering if there is a good way to make an optimal timing files with a mixed design (e.g. using make_random_timing.py). For example, I have two types of stimuli, say A and B, and each type has three conditions (A1, A2, A3, and B1, B2, B3). In a run, A and B are separated with different blocks, while within the block, the three conditions are played randomly (with jitterred interval between two trials). The order of blocks are also random, but the interval between two adjacent blocks might be small (e.g. 4s, or the averaged interval between two trials in the block).

Or does it make sense to create and evaluate the timing across the whole runs in such a design?

Thanks!

Qiuhai
