Hello,

First of all I would like to thank you very much for developing such a great toolbox.

I wanted to see 1) the change in connectivity over time, and 2) the difference between groups in the connectivity change.
With the help of many questions here and Prof.Zalesky, I was able to build a design matrix for 2 group, 2 session (attached).
I was referring to the following link (https://www.nitrc.org/forum/forum.php?th...).

I have some questions here.

1. Did I build the interaction column correctly?

If so:
2. The interaction is determined by group x time, I was wondering how the interaction was determined here? (with control=0 and patient=1?)
3. if this interaction is significant, I'm wondering how to interpret it. I'm confused about time1 for control and time2 for patient being tied to the same 1.

Thank you so much for the help.

Chris
