Hi AFNI experts,

I'm trying to set up a couple of reliability analyses but there are some details that I'm not sure about.

I'm referring to the HBM paper (https://doi.org/10.1002/hbm.23909) and AFNI documentation on 3dICC (https://afni.nimh.nih.gov/pub/dist/doc/program_help/3dICC.html)

1. I'm trying a whole brain ICC, and I'm then planning to use ICC(3,1). The paper lists 4 model strategies, some with and some without regularization. I don't see how I can set up, for example RME with 3dICC.
Am I missing something here? is it possible to set up these model strategies or not? if not, what is 3dICC using then?

2. I have a very similar data set to the one described in the HBM paper. I'm interested in the reliability of emotional effects (e.g., Emotional vs Neutral, or Pleasant vs Unpleasant). Something similar to what done here: [doi.org]
What is the InputFile for -dataTable? a tFile for the contrast of interest for each subject?

thank you,
ns
