Hi Guang,

Depending on what you do you can choose different routes. Note, for both
of these you first need to run the new timepoint cross sectionally (step
1 in the description
http://surfer.nmr.mgh.harvard.edu/fswiki/LongitudinalProcessing ):
recon-all -all -s newtpid -i path/to/dicom

Here are the two options once the cross sectional results are there:

1. you have only very few timepoints in the base/template so far (2 or
3). In those cases I would recommend to rerun the base and rerun all the
longitudinals with the new and more accurate base. The commands are on
the Wiki and are the same as usual.

2. you have many time points in your base, the additional time point is
not likely to change the base much. In that case you can simply 'patch'
the base without reprocessing and only run a single longitudinal run. 

Let me know if you want to go route 2 because I am writing a script to
patch the base (there are a few files that need to be added so that the
longitudinal run will go through). If there is demand, I will put
priority on this and make it available.

Best, Martin
