clustering correlation with voxel seed

What is the proposed method in AFNI for clustering the correlation with a seed voxel?

3dTcorr1 doesnot mention what to do to choose cluster size so here is my workaround:

use 3ddeconvolve to get the R^2 of brain with the regressor being the seed voxel, get correlation coeficient from R^2. Use the residuals in 3dFHWMx and 3dclustsim to find the cluster size for a particular FWE.

What is the input data?
Is it a single subject time series?
and the output that you want is a data set that can be thresholded in the afni gui?
Can you send the 3dinfo -verb output for the 3dDeconvolve output dataset?
Thanks, Justin
