Dear Friends:
I'm trying to assess if there is a difference between control and
patients in correlations between RT and changes in BOLD signal. I'm
using multiple correlation with constant. Could any one tell me if
following procedure is correct:
1. select multiple correlation with constant
2. select the con images of the control and patients
3. select 4 covariates.
4. enter 1 1 1 1 ... 0 0 0 0 ...
5 enter 0 0 0 0 ... 1 1 1 1...
6. enter RT and 0 0 0 0...
7 enter 0 0 0 0 ... and RT
Best
