Hello everyone!
I have done group analysis with the full factorial design (contrasts with 8
different conditions versus Rest were taken from the first level). If I make
the contrasts between some of them I do not get significant results. I tried
another way to find a difference between conditions: masked exclusivly
one contrast (condition1-Rest) with the other (condition2-Rest). I have got
a nice results with significant voxels, but I wonder if it is a legal way to
show the difference between conditions.
Would I get the same results just contrasting 2 conditions in convetional
way if I did not have a power problem?
Thank you very much in advance,
Elena
