Dear all,
We would like to use AFNI's AlphaSim to determine a cluster extent threshold to use in a VBM analysis.
We were wondering whether it is appropriate to use an AlphaSim-determined extent threshold on VBM data that has been corrected for non-stationarity. That is, does the non-stationarity correct estimates of cluster size, thus rendering the data isotropic, or does it only correct the cluster p-values?
Thanks for your help.
Paul
