Dear freesurfers, I’m using mri_glmfit to estimate the correlation between a time series from a seed region and all the voxels in the brain. For one subject I get values in the pcc.nii.gz around .4 in my region of interest (not seed) but the z-scores are extremely high, i.e. > 4. Am I doing something totally wrong? My understanding was that z = arctanh(r).
Thank you so much again! Lauri Tuominen
