Dear FSL community,
I am trying to compute "manually" the zstat map of an higher level analysis (FLAME 1) corresponding to a one sample t test using first level data. So, having the cope of each individual, is the zstat at group level equal to mean(cope)/sqrt(mean(cope))? I am considering the reference "General multilevel linear modeling for group analysis in FMRI"by Christian F. Beckmann et al. How is computed the variance of mean cope in the case of FLAME 1?
Thanks,
Angela
