1) If my voxel size is 3.475x3.475x4, it should be face (NN6) connection? Can I check how I can calculate the rmm value?
2) I used alphasim and obtained these:
Gaussian filter width (FWHM, in mm) = [1.524, 1.389, 1.300]
Individual voxel threshold probability = 0.050
Number of Monte Carlo simulations = 1000

12 2 1.000000 0.000000 2 0.002000
My question is based on this, cluster size will be 17, as a rule of thumb, if the cluster size is equal to or bigger than alpha, then the results are okay to use?
Thank you for your help and time.
