Hi there,
I'd like to do something like an exclusion analysis similar to a conjunction analysis using our fMRI data. Not sure if that makes sense... I'd like to identify structures that are only activated in one group. Each group has 2 sessions, before and after treatment. I came up with an idea as follows:
1.) conjunction_1 = group1_before intersected with group1_after intersected with group2_before intersected with group2_after: shows were both groups are active
2.) conjunction_2 = group1_before intersected with group1_after: shows were group 1 is active
3.) group1_unique_bin = conjunction_2_bin - conjunction_1_bin
4.) group1_unique = conjunction_2 * group1_unique_bin
would that be a way to do it?
Thanks for any comments.
Cheers,
Torsten
