Dear all,
Could I just do this by replacing the corresponding column of SPM.xX.X
with my own reference function? Like in my experiment, there are two
conditions baseline and task, and I modeled them explicitly during setting
up the design matrix. The reference function reflects the global fluctuation
time course. Should I just replace the task associated column in SPM.xX.X or
should I change the model to just explicitly specify the task condition (so
there will be only one condition modeled in the SPM.mat) and then replace
the column in SPM.xX.X?
Thanks.
