Hello,
I have data from a 2x2 repeated measures design (Time: Pre, Post, Condition: A, B) and I performed a group level analysis using 3dANOVA3 -type 4 -alevels 2 -blevels 2.
My question is how do I best display which regions showed a significant difference with respects to group and time and in what direction? Is it appropriate to create a mask based on the time_cond_interact map and then use 3dcalc to look at PrevsPost difference for the A and B condition separately only within the significant interaction mask? Or should I use the condition effect map as a mask and then use 3dcalc to look at PrevsPost difference only where there was a main effect of condition? Or is there another option that is more appropriate?
Thanks
