Three Groups Analysis
Finally I am succeed to pre-processing in Slicer 4.5.0.1 in OS X and run MANCOVA-wizard in Ubuntu,
However, when I try to 3group MANCOVA (group column is coded as 1,2,and3), it gives error.
Does MANCOVA only supports two group analysis?

data in group_type 0 has been relabeled: 1 --> group A = -1 ; 2 --> group B = 1

RE: Three Groups Analysis
Thanks, 
Than, is there any method to run 3-group MANCOVA?

RE: Three Groups Analysis
None of our tools currently support it. The best our tools can offer would be to do 3 2-group analyses (A vs B, A vs C, B vs C). If you are statistically savvy enough then you could import the surface data into R and do a vertex-wise analysis there
