Hello, I am new to Homer3 and I am going through the trainings (2021).
I am using Homer3 (v1.80.2) which allows to specify the session functions.

I noticed that hmrE_RunAvg and hmrS_SessAvg have pretty similar descriptions:
hmrE_RunAvg: "Calculate avearge HRF of all runs for one subject."
hmrS_SessAvg: "Calculate avearge HRF of all runs for one subject."

The questions are:
does hmrE_RunAvg compute the average for each subject's session?
does hmrS_SessAvg compute the average of the sessions averages or compute the average of all runs across all sessions? Say a subject has two sessions with one run in session1 and two runs in session2, does hmrS_SessAvg average the mean of the two sessions or averages the 3 runs?

Thanks
