1. Cross-sectionally process your data (recon-all)

2. Create template for all timepoints for each subject.

recon-all -base <templateid> -tp <tp1id> -tp <tp2id> ... -all

3. Longitudinally process all timepoints

  recon-all -long <tpNid> <templateid> -all

4. Inspect the base and longitudinal data
