Hello AFNI experts,

I have 60s stimulation duration in a scan session. I plan to use two 30s block stim function (early stim func= BLOCK(30,1), late stim func= BLOCK(30,1)) option for the total 60s stimulation.

My question is for the early stim function BLOCK(30,1), does that consider the later 30s of stimulation as OFF (which is basically stimulation ON) and the same way for the later BLOCK function, does it consider the early 30s of stimulation as OFF?
