Dear all,
I created the design.con file using the command: "Text2Vest contrasts.txt design.con" .
The contrasts.txt file looks as follows:
1 -1 0 0 0 0
-1 1 0 0 0 0
0 1 -1 0 0 0
0 -1 1 0 0 0
1 0 -1 0 0 0
-1 0 1 0 0 0
(I am comparing 2 by 2 three groups and I have 3 covariates)
But when running "Text2Vest contrasts.txt design.con", I get the following:
/NumWaves 36
/NumPoints 1
/Matrix
1 -1 0 0 0 0
-1 1 0 0 0 0
0 1 -1 0 0 0
0 -1 1 0 0 0
1 0 -1 0 0 0
-1 0 1 0 0 0
Which I believe is not correct.
1. Shouldn't it be:
/NumWaves 6 (columns)
/NumContrasts 6 (cause 6 contrasts)
/PPheights ???
/Matrix
1 -1 0 0 0 0
-1 1 0 0 0 0
0 1 -1 0 0 0
0 -1 1 0 0 0
1 0 -1 0 0 0
-1 0 1 0 0 0
2. What should go after PPheights?
3. When creating my design.mat file using Text2Vest, this looks like this:
/NumWaves 6
/NumPoints 54
/Matrix
1 0 0 96 1 1.32
1 0 0 99 0 1.13
1 0 0 97 0 0.77
1 0 0 101 1 2.12
0 1 0 126 1 1.42
1 0 0 120 0 0.98
1 0 0 152 1 2.17
1 0 0 119 0 1.42
1 0 0 134 1 1.05
etc.. (54 lines corresponding to participants).
Is this correct or should I also add a "PPheights " line? If yes, what should this contain?
Thank you in advance,
Ariadna
