Using 3dLME for classic ICC analysis

Hello Afni Experts,

I’m interested in doing two way mixed effects average measures ICC (3,2) on a dataset where I have two contrasts of the same type, each derived from scans collected on different days.

Would the -ICC option in 3dLME suitable for this or do I need to use an older script (3dICC…?)? If in 3dLME I specified -ranEff “Subjects” and -model “Session”, would this achieve the desired result (sessions as fixed effects)? If not, can someone please help with how I could set this up in 3dICC.R?

Thank you!
