Examples of using Onyx

Hello,

I'm a novice in structural equation modeling. I am curious if Onyx works for the following experimental design:

There are 2 treatment variables (T1, with 2 levels; and T2, with 3 levels; each with 3 replicates) and 3 response variables (R1, R2, R3). I'm interested in how each of the T variables affects the R variables, as well as if this relationship changes depending on the level within each T variable. I'm also interested to know how R3 is related to R1 and/or R2.

I would like to repeat this simple design with more replicates and more R variables later. I tried putting the data in Onyx with help from the guide but wasn't sure how to specify some of the variables/paths and other options to see the relationships quantified...

Thanks for any input.

Here is some sample data with this design:
