Hi, I want to use FreeSurfer to analyze a longitudinal study. For each subject in my study, I already used FreeSurfer 4.2 to perform the cross-sectional analysis. However, FreeSurfer 4.2 did not have a longitudinal pipeline. Therefore, I want to use FreeSurfer 4.5 for this purpose (in the FreeSurfer wiki, it said the longitudinal pipeline in 5.0 is broken). My question is: A) Should I redo the cross-sectional analysis using FreeSurfer 4.5 OR B) I just run 'recon-all -base' and 'recon-all -long' using FreeSurfer 4.5, based on the cross-sectional results from version 4.2.

Thanks, Rong
