Dear All,
Our experiment is event-related, with TR=2 sec, and 6 EVs. We would
like to use FIR basis functions.
From reading the archives, I saw that one could set the window length
to cover the normal haemodynamic rise and fall time and that the
number of functions is one TR long.
So for me that would could mean using a 14s window and 7 functions or
16s and 8.
1) What is the disadvantage of having a long window and a greater
number of functions?
2) Are there any guidelines for what to set the Phase at?
Thank you very much.
Michelle
