Hi,

I’m trying to set up my fsgd file for repeated measures ANOVA with two groups and 6 time points (0, 1, 2, 3, 4, 5) by following the example from here: http://surfer.nmr.mgh.harvard.edu/fswiki/RepeatedMeasuresAnova

Does this look correct for the fsgd file?  Subject 2 is missing time points 2 and 5.

GroupDescriptorFile 1
Title	RepeatedMeasures
Class	Group1
Class	Group2
Variables			TP0-vs-TP1	TP0-vs-TP2	TP0-vs-TP3	TP0-vs-TP4	TP0-vs-TP5
Input	subject1_tp0	Group1	1	1	1	1	1
Input	subject1_tp1	Group1	-1	0	0	0	0
Input	subject1_tp2	Group1	0	-1	0	0	0

Input	subject2_tp0	Group1	1	1	1	1	1
Input	subject2_tp1	Group1	-1	0	0	0	0
Input	subject2_tp3	Group1	0	0	-1	0	0
Input	subject2_tp4	Group1	0	0	0	-1	0
Input	subject3_tp0	Group2	1	1	1	1	1
Input	subject3_tp1	Group2	-1	0	0	0	0
Input	subject3_tp2	Group2	0	-1	0	0	0
Input	subject3_tp3	Group2	0	0	-1	0	0
Input	subject3_tp4	Group2	0	0	0	-1	0
Input	subject3_tp5	Group2	0	0	0	0	-1

I’m interested in the overall group effect [1 -1 0 0 0 0 0 ], overall time effect, and group-x-time interaction.

Is this the correct contrast for the overall time effect?

0 0 1 0 0 0 0

0 0 0 1 0 0 0

0 0 0 0 1 0 0

0 0 0 0 0 1 0

0 0 0 0 0 0 1

What would be the contrast for group-x-time interaction?

Thanks!
