Hi,
this is no issue. Everything will be taken care of by the copes/varcopes.

Betreff: [FSL] FEAT model set up with Block design with irregular block spacing
Hello everyone,
I am analyzing an fMRI data set with two runs, each with two stimulation conditions (A,B). Each block of stimulation is followed by a shorter block of baseline fixation.
However, the spacing varies between block types over the run.
Example, for subject 1:
Run1: ABBA BAAB
Run2: BAAB ABBA
So we can see that the spacing between 'A' blocks is not regular over the run. Should this be a source of concern?
Is it possible to set up the EVs in FEAT model set up to reflect this irregular spacing between block types?
Thanks
