There are two regressors in the model at the first level. I do a [1 0] and
a [0 1] contrast and also an F-test. This is done for several functional
runs. I then do a standard fixed effects analysis at the 2nd level for each
regressor and a group analysis for the F-test using sum(Z)/sqrt(n).
Finally, I count the number of significant voxels at the 2nd level for each
regressor and compare with the number of significant voxels in the F-test.
