I have 2 questions.
I ran 3dLME and used the -resid option (-resid resid+tlrc) to be able to estimate the cluster size for thresholding.
First, I was gonna estimate the noise smoothness with 3dFWHMx -ACF NULL -automask -input resid+tlrc and then estimate the cluster size for thresholding via 3dClustSim -acf 0.591509 4.9806 13.8274 -mask mask+tlrc.
But the output of -resid confuses me.
There are as many subbriks as input files in 3dLME and I don’t know which one to use in 3dFWHMx -ACF NULL -automask -input resid+tlrc[WHICH SUBBRIK?]
Below is the output I have from 3dFWHMx and I’m using these 3 numbers as input to. 3dClustSim -acf 0.592517 4.97794 13.8289
Are these the 3 numbers I should use?
