The fwhm.dat file contains the total amount of smoothness. The data have inherent/endogenous smoothing and then you apply a certain amount, so the total amount is different (more than) the amount you applied. To do correction for multiple comparisons, mri_glmfit-sim needs to know how smooth you

Hi, I have a question about mri_glmfit. As an input, you give e.g. the stacked thickness data from all subjects, smoothed with a certain fwhm. But then as an output file, it gives an fwhm.dat file, which, at least in my case, contains another smoothing level. I noticed this because I ran mri_g

Hi, using version 4.0.5 i ran the command: mri_glmfit --y qdec/N83_only_boys.mgh --fsgd qdec/qdec.fsgd doss --surf fsaverage lh --C qdec/diff-1-2.txt --glmdir stats/ it worked. then i did: mri_glmfit --y qdec/N83_only_boys.mgh --fsgd qdec/qdec.fsgd doss --surf fsaverage lh --C qdec/diff-1-2.tx
