Hi all,

I'm having a problem with specifying my conditions. I have three conditions (placebo, condition 1, condition 2), and (in most cases) three sessions (A, B, and C) - so far, the matching is easy; I just select the condition and then input the onset and duration for each session (0, infinite and so forth).
However, for a few atypical subjects, I had one condition twice with another one missing, for example:
instead of placebo, condition 1, condition 2, I had something like placebo, placebo, condition 1.
I assigned the sessions accordingly, but when I extracted the ResultsROI_Subject*_Condition*.mat files, I noticed that for these atypical subjects I only had one mat file for placebo (instead of 2 - since there were 2 placebo sessions), one for condition 1, and an empty file (NaN in each field) for condition 2.
My question now is: was the second placebo .mat file simply overwritten by the first one, or did conn compute an average for the two placebo runs?

Any help is greatly appreciated,
Best wishes,
Charlotte
