And in general, I think it is a
bad idea for someone who does their entire analysis, including group statistics, in FSL or SPM or any other package, to turn to 3dClustSim to validate their results.
In the near future, I am going to disable the Gaussian spatial autocorrelation function (ACF) option in our clustering software, and only allow the use of the more complex "mixed" ACF model, which is usually more conservative.
Even then, I would only recommend use of our model for cluster thresholding when the group analysis is done with one of our programs (e.g., 3dttest++). Any other use 3dClustSim even with the ACF option strikes me as getting close to "shopping" for results.
