Hello experts.
I have now difficulties using one of basic functions: finite impulse
response(FIR).
When adopting FIR, SPM2 requires some parameters.Particularly, I am not sure
what the length of time indicates.
1) Would anyone tell me how to calculate those numbers from the design?
2) Does anyone know theoretical/mathematical backgrounds of FIR?
My design is:
TR = 14 sec, TA = 3 sec, stimuli = 3 sec
MRI scan >> 7sec >> stimuli >> 1sec >> MRI scan >> ...
Any advice is helpful.
Thanks.
