Dear all,
I need to specify this matrix as my F contrast [1 -1 0; 0 1 -1] , however I'm not sure how I can do this. Usually for a matrix like [1 0 0; 0 1 0] i use mkcontrast-sess -analysis analysis-name -contrast ftest -a 1 -a 2 -nosumconds I can use -c for -1 in the contrast, but using nosumconds, will assume that -a and -c are from different contrasts, so this does not work apparently -a 1 -c 2 -a 2 -c 3 -nosumconds because each a and c are assumed to be from different vectors, not from one vector. I'd appreciate if anyone could help me. Best wishes, James
