Dear SPM -list
Could someone please clarify the definition of window length in FIR
analysis. According to the SPM5 manual, window length refers to the length
seconds of the post-stimulus time window that the basis functions span.
Does it mean:
1) the time between stimulus presentation and the onset of scan (the onset
FIR basis function)
2) the length of the basis function itself? If the latter, how should we
thanks in advance.
