Hi Anderson,
I had a question on how PALM interprets multiple contrast corrections:
ContrastName1 Group1 > Group2
/ContrastName2 Group1 < Group2
/ContrastName3 Group1 > Group3
/ContrastName4 Group1 < Group3
/ContrastName5 Group2 > Group3
/ContrastName6 Group2 < Group3
/NumWaves 9
/NumPoints 6
/Matrix
1 1 -1 -1 0 0 0 0 0
-1 -1 1 1 0 0 0 0 0
1 1 0 0 -1 -1 0 0 0
-1 -1 0 0 1 1 0 0 0
0 0 1 1 -1 -1 0 0 0
0 0 -1 -1 1 1 0 0 0
Is this interpreted as 6 one-tail tests or does PALM automatically group these so that they are 3 - two-tail test. The reason why I ask is that I am not sure if the cfwe files are corrected for 3 contrasts or 6. If it is corrected for 6 contrasts then would I set each contrast threshold alpha=0.1 such that the overall two-tail is 0.05?
Thanks
Ajay
