Hi all
Our question is how to get a map reflecting the correlation between one
region and the whole brain.
Specifically for spm5, for a given coordinate, we want to see the
correlation between this coordinate and the whole brain. It is said that we
can get the time course of this coordinate and input it as a covariance
(1st-level analysis->Data & Design->Condition->Parametric Modulations).
However, data input here is related to events or blocks defined in
"Condition". For example, 50 events are input in
"Condition->Name(Onsets,Duration)" and 50 reaction time are input in
"Parametric Modulations". Now, if we input the time course (196 sample
points) in "Parametric Modulations", what to input in "Condition"? If this
is not the way to do what we want, what's the right way in spm5? Thanks a lot
