Dear Eugenio,
the exchangeability blocks depend on the design and finally on the defined contrast and there is no way to change the exchangeability blocks manually. However, you can send me the SPM.mat of your design and I can check the shuffling of the data.
Best,
Christian

I'd like to define exchangeability blocks to prevent groups of subjects being shuffled - I'm testing a genetic disorder, where healty controlsm patients and first-degree relatives provide data. I can't reshuffle the last two groups freely because of their relatedness.
