Hi All,

I have processed some longitudinal data (0, 1 week, 4 weeks) using the advised longitudinal stream. This is a healthy control sample and I wasn't expecting to see any differences in cortical thickness over the time points.

Looking at some of the measures I have noticed that something doesn't seem quite right 

e.g. for one subject the insula measures:

                    Cross-sectional     Longitudinal    Base 

A                    2.835                    3.016

B                    2.721                    1.864

C                    3.050                    3.107

                                                                              3.098

The majority the longitudinally processed data looks reasonable, but there are a few instances where one timepoint looks completely different.

Do you have any ideas if something may have gone wrong? I have attached the recon-all.log files for the template and the 3  longitudinally processed timepoints.

Thanks in advance for your help,

Amanda
