Hi Caspar, there are a couple of things you can do:
1. Go into the mri_glmfit folder used to create the input contrasts to the conjunction. Create a subfolder. Save the conjunction as sig.mgz and create a file called "C.dat" (it can be empty) in this folder. Then run mri_glmfit-sim specifying to do the simulation rather than using cached data.
2. Create cached data by running mri_mcsim. This may take longer than #1, but once you have the cached data you do not need to run it again, which could be useful if you are going to do more analyses with this template

Hi, I have a question regarding cluster size thresholding using mri_glmfit-sim. Namely, I have a sig.nii conjunction map that I made with mri_concat. The analyses that serve as input to the conjunction map are done on a custom surface template. If I want to run mri_glmfit-sim, how would that work? I obviously do not have precached data. Thanks, Caspar
