Hi,
I am a fairly new FSL user. I am comparing pre and post scans. The design is relatively simple in that a base scan is taken before a treatment and then a second scan is taken after treatment.
I would like to know if I am setting up the GUI correctly to do a 2nd level analysis.
There are two groups- control & treatment
There are two sets of scans- pre & post
For the first level analysis, I am setting up my pre-scans as having an empty shape and calling this explanatory variable X1. For my post-scans I am also setting this to have an empty shape and calling this explanatory variable X2.
After I have collected the first level analyses, I plan on doing the group comparisons. Where a new explanatory variable of group inclusion will be added. In the end, my main variable of interest is the interaction between the treatment group and the pre-post scans.
Thanks!
Jaret
