Hi Luke,

if T1A is your first time point and T1B the second, you need to do the second (create a directory for each). The first is doing something very different, it is using both inputs for a single reconstruction, by averaging the inputs.

Best, Martin

Hi folks,

sorry it's me again with a very basic question. What is the best way to import longitudinal data?

recon-all -i /path/T1A.nii -i /path/T1B.nii FIRSTSUBJECT

or

recon-all -i /path/T1A.nii FIRSTSUBJECT_A
recon-all -i /path/T1A.nii FIRSTSUBJECT_B

I tend to use the second choice because otherwise I would have no idea how to distinguish between SUBJECT-ID and TimepointID later on in the processing stream.

Best whises,

Luke
