I would like to present a question concerning proceeding from ANOVA to
We have performed analysis analogous to the ANOVA 1 factor 4-levels example
in FEAT manual (in our case 3 levels) and in the resulting F-statistic
certain areas survive the significance threshold used.
In an analysis analogous to the pairwise t-test example in FEAT manual we
see that in one of the comparisons between two levels there are voxels that
survive the thresholding and overlap those seen in ANOVA. In addiotion there
are activated voxels outside ANOVA areas.
Should we use the ANOVA thresholded activation as mask for pairwise
comparisons using t-test (i.e. should we discard voxels from further
analysis that showed no effect in ANOVA), and if so, how to correctly set up
