Hi,

I'm doing a seed-voxel analysis, and I ran an ANCOVA that has 3 groups and 4 second-level covaraites. I got a few significant overall effects, and I want to now do post-hoc comparisions to look at where the group differences are. I used the import values option to extract the connectivity values, and was planning to either do the post-hoc between-group comparisons using the calculator tool or with external software. However, do I need to re-control for the covariates when I do my post-hoc comparisons? I'm a bit confused on if the connectivity values that I'm importing are controlling for the covariates already, or if they are the raw values and the covariates were only used in calculating the general ANCOVAs, and I'll need to include the covariates again if I use the calculator tool/external software. Thank you so much for any help you can offer!
