Shall we click the button "Estimate smoothness on statistical image directly" before computing results for GRF correction?

 

Dear all,

When we review the results using GRF correction, if we click the button "Estimate smoothness on statistical image directly" before computing results, we would get fewer but more significant clusters, shall we or shall we not click the button before computing?

Best regards and thank you very much.

If the smoothness is already estimated by DPABI Statistical Analysis module, then it's more accurate than "Estimate smoothness on statistical image directly", as the smoothness is estimated based on 4D residual images.
