RE: Cluster and voxel level correction of PPI
A gPPI/PPI Analysis has the same second-level analysis as
activation analyses.
(1) Get the 1st level con_ images;
(2) Compute 1-sample/2-sample t-tests on the con_ images across subjects;
(3) Threshold the results.
The correction options are the same as activation studies. In SPM, you have cluster FDR, topological FDR, or using the cluster extent as determined by 3dClustSim from AFNI.
