Hmmm. I don't know that Caret can do this. There are several cluster-based tests that find the minimum area required to correct for multiple comparisons, given an input cluster-forming threshold (say, t=+/-3.0):
caret_command.txt: caret_command -metric-statistics-anova-one-way caret_command.txt: caret_command -metric-statistics-anova-two-way caret_command.txt: caret_command -metric-statistics-coordinate-difference caret_command.txt: caret_command -metric-statistics-interhemispheric-clusters caret_command.txt: caret_command -metric-statistics-one-sample-t-test caret_command.txt: caret_command -metric-statistics-paired-t-test caret_command.txt: caret_command -metric-statistics-two-sample-t-test These are permutation tests that find the smallest alpha*iterations cluster at the specified threshold. And they output a paint/region file showing the clusters that survived significance cut-off. But interactively in the GUI, I'm not aware of such a feature. If you've checked the metric/smoothing dialog, then Surface: Region of Interest is the other place I'd look. And I don't recall it. Since we adopted TFCE, we don't use the cluster-based tests anymore.
