Dear experts,
(1) in an epoch related design with 2 baseline conditions (B1 & B2) and
2 active tasks (A1 & A2), both of the latter parametrically modulated,
is there any reason why to avoid varying epoch lengths? Both A1 & A2 may
make it psychologically sensible to employ epochs of different duration.
In addition, I thought it may be helpful to exclude errors introduced by
drifts at low ferquencies. Is that correct?
(2) how to get SPM to help with setting up a paradigm design?
TIA- andreas
