Hi FSL users, I am trying to find out the minimum size of a cluster admitted to my activation map given my post-stats thresholding of z=2.3 and p=.05. I've gone over a bunch of the papers suggested in the archives here but can't figure out actually how to calculate this for my data. How, if at all, is the p-threshold related to my RESEL count? Thanks for your help.
