Ran a bunch of MCA replications of structural processing, on 7 T1-weighted images.
Derived a test at each voxel -> p value. Also tried applying different FWE and FDR correction for multiple testing.
Main experiment is "global null", leave-one-MCA-replication-out experiment.
Varying the alpha threshold, the proportion of (false) positive detections follows the nominal value closely (YAY)
With FWE correction, most replicates lead to no detection at all, as expected. PB: need to compute the empirical FWE to compare with the nominal value.
