Dear Douglas,
Sorry to bother you with this, but after reading the thread about the Eklund papers I'm getting confused about what I actually did when correcting for multiple comparisons and I'd also like to know whether I'm on the safe side. I used pre-cashed Monte Carlo simulation with a cluster finding threshold of 0.05 (at least so I thought): mri_glmfit -sim - -glmdir - -cache 1.3 abs - - cache-dir - - cwpvalthresh 0.01 Am I correct? And am I also correct that the FDR may be about 13% instead of 5% when doing this? (I smoothed thickness and surface area data with FWMH 10mm, but not the lGI data, because they were already very smooth and pre-cashed simulation didn't work after additional smoothing). Thanks, Maaike
