You need to set up the psdwin to span the duration of a hemodynamic
response to your event as if it were presented in isolation. For a 3sec
event, you can probably use something like 24 sec (so min=0, max=24).
Since your TR=2, but your event duration is 3sec, I'd set dpsd=1 (so
that both the
Hi,
I have 2 questions.
1) How do I calculate psd min, max, and dpsd. Is there a formula for
calculating these values? I have 4 kinds of stimuli, stim duration = 3s,
stim repetition = 25, TR =2 so:
optseq2 --ntp 180 --tr 2 --psdwin [?] --ev A 3 25 --ev B 3 25 --ev C 3 25
--ev D 3 25 --o
