I was looking at the suggested processing stream for using 3dFWHMx and 3dClustSim and just wanted to check and see if I’ve got it straight.
- Using -errts in 3dDeconvolve (for instance) get residuals for each subject.
- Run 3dFWHMx on EACH TR in the errts file for each subject, excluding trails that are censored.
- Append the 3 output parameters (a,b,c) to a .1D file for each subject.
- Get the mean of these 3 parameters in the .1D file for each subject.
So: at this point, I will have 3 parameters for each subject. Now - do I average these across subjects to get a final a,b,c to supply as arguments in the -acf parameter in 3dClustSim?
