Dear Freesurfers,
I'm going to run 1-way anova, followed by post hoc pairwise comparison. My "factor-of-interest" has 4 levels and, in addition, I would like to regress out the effects of 3 continious variables. I have attached my *fsgd-file. Therefore, my first *mtx-file should contain the following:
0.5 -0.5 0.5 -0.5 0 0 0 0 0 0 0 0 0 0 0 0
Correct? Thank you very much beforehand! === Regards, Alexander Lebedev Stavanger University Hospital
Hi Alexander, what you have there looks like an interaction test for a 2x2 ANOVA. If you are looking for an effect of level, then you will need something like 1 -1 0 0 1 0 -1 0 1 0 0 -1 Plus 12 zeros on each line for the covariates. I would also first test for an interaction in the covariates. If there is no interaction, then re-run with a DOSS model.
