[Freesurfer] Longitudinal analysis question

Hello FS experts,

I am running a group up subjects pre/post treatment.

When trying to do group analysis, after converting data with the mri_slope command, when I made the long table into a cross table, I noticed in qdec it averaged my "time" variable and only supplies a mean and there is no longer separate timepoints for subjects, just one value per subject. Do I need to define time as something more descriptive than 0 (tp1) and 1 (tp2)? I am so close to analyzing these data, just need a little help with the group analysis

Thanks
