I am trying to do a regression analysis looking at fMRI activation and behavioral performance. When I try to run 3dRegAna, the program aborts with the error message:
++ 3dRegAna: AFNI version=AFNI_2007_05_29_1644 (Aug 7 2007) [32-bit]
++ Authored by: B. Douglas Ward
missing ':' between sets of -model parameters
(is ':' attached to a number?)
3dRegAna Error: bad -model usage
I have copied the script below. I only have one non-constant predictor so I was under the impression the model should be 1:0, but I must have this wrong.
Thanks! Jennifer.
