 design matrix generation

Hi,

I am trying to generate a design matrix. I think I cannot use RSFgen for my experiment: Random permutation method is not suitable, because the order of the conditions is fixed. I also cannot use Markov Chain method, because certain conditions depend on what condition was "chosen" several steps before (not only on the immediately preceding condition). For example, E follows D, but only if B followed A.

I basically have the following four types of trials:

A B C D E F
A G C D H F
A B I D J F
A G I D K F

I really only can randomize for how long a condition is on (number of TRs). Condition A can be on for 1, 2, or 3 TRs; condition B - for 2, 3, or 4 TRs, etc.

So I was wondering what I can use to create a design matrix for my experiment?

Thanks,
Alena.
