Hi - I'm not quite sure what you are describing here - possibly you
are saying that you have created a 4D NIFTI file that somehow
summarises previous analyses of responses to some stimulation..? In
which case if you have a model you want to test against that - you can
create the model (e.g.) with the Glm tool, and then test the data
against that using randomise?
Cheers.
