from mri_glmfit-sim --help csdbase.sig.voxel.mgh - the sig volume corrected for multiple comparisons on a voxel-wise basis. The threshhold and sign are irrelevant. The value at each voxel is the corrected -log10(p-value) for that voxel. It is computed from a simulation in which gaussian nois

External Email - Use Caution Hi, I was wondering if anyone knows how the numbers in cache.th40.pos.sig.voxel.mgh are computed, or where I'd look to learn this. There is a one-liner in the documentation
