Hi Doug, thank you very much! I have two follow-up questions for your two suggestions: 1) If I want to use mri_glmfit-sim but my conjunctions are not from contrasts that are all from the same GLM, I guess I can still do what you suggested but I will have to come up with a fwhm.dat for the conjunction, correct? Is there a way to compute this from the conjunction sig map, or should I use the average or the max or the min of the contrasts that go into the conjunction? This is for functional data.
2) It seems that there is a version of mri_mcsim that allows one to specify a range of FWHM with the flag --fwhm-max; however, version 1.17 that comes with the 5.1 and 5.3 releases does bot have that option. Is the version of mri_mcsim that understands --fwhm-max available?
