Dear all,
I have a very basic question about the functioning of Randomise. I was wondering if running the randomise function one sample t-test using
randomise -i OneSamp4D -o OneSampT -1 -T
With the data of one group in 'OneSamp4D'
Gives the same result as running a ‘fake’ two-sample t-test
randomise -i TwoSamp4D -o TwoSampT -d design.mat -t design.con -m mask -T
With the data of both groups in ‘TwoSamp4D’
design.con = [0 1]
and design.mat e.g. [0 1; 0 1; 1 0; 0 1; 0 1; ...];
In a (recently developed) toolbox I’m using they implemented the second way, but I wanted to make sure that Randomise performs sign flipping to calculate the clusters, as it would in the first way.
Thanks a lot,
Lars
