Just look for positive activation. The p-values were computed assuming two-sided, so if one-sided is really what you want, divide the p-values by 2. Note that the correction for multiple comparisons (mri_glmfit-sim) will do this for you automatically when you specify a signed test doug

Hi,

How would I make a one sided t-test to see whether group mean is greater than X (any other number than 0)?

Thanks, Dace
