The time between scans is not relevant to the longitudinal stream itself. You may need to model the data differently when you go to perform a statistical analysis.

Hello all,

I am hoping to do some longitudinal processing on a dataset. However, the intervals between time points for each subject are not uniform. Can freesurfer's longitudinal processing stream handle this, or do all of the time points need to be equal?
