I know that it is possible to submit data with only one timepoint into
the longitudinal stream with FreeSurfer 5.2. My question is, what is the exact command?
is it:

1) recon-all -base <templateid> -tp <tp1id> -all
or
2) recon-all -base <templateid> -tp <tp1id> -tp <tp1id> -all

I have accidently run them with the second command, and I am also wondering
whether this will have a negative impact?

Thank you for your time and consideration!

Sincerely
Luigi
