Dear Freesurfer team,

In the mri_glmfit-sim summary output file, I get a number of output variables, and I'm not sure what some of them are. Could you explain the ones in bold to me?

I know CWP stands for Cluster-wise P-value. But what is the low and the high number, a confidence interval? And isn't it odd that my p-values are (almost) 1?

Thank you in advance.

Kind regards,

Rose
