Hello Experts,

I am wondering if any of you are aware of any commands of optseq for a mixed design? We are specifically not sure how to specify block duration. It seems like optseq is designed for event related design according to the help page, but I checked some community blogs and it looks like there should be some commands for mixed block event related design.

There are four blocks of 6 images each.

1) Surprise/Embarrassment faces

2) Happy/Sad faces

3) Identify gender of faces

4) Match shapes

We planned to have the Match shapes blocks to interleave all other blocks. Thank you in advance!

Best,

Yu
