Dear Gabor,
Thank you for the quick response and apologies for my misuse of terms.
I modeled each trial separately as
a single epoch. In other words, I compared 1) and 2).
Best,
James

As far as I know mini-block design means that you have a short block with several trials, and you might want to model the whole block as a single epoch or every trial separately. But you talk of different durations for different trials, which I understand as if you are ondering whether to use a fixed duration or a variable duration.
