[Freesurfer] Question about "Getting started with your own data"

Hi freesurfer gurus,

We are trying to do reconstruction in tksurfer section according to the text. We have a question in "Getting started with your own data" section.

In the text, the following commands are written,

recon-all -s <subjid> \ -i <path_to_dicoms>/95555-2-1.dcm -i <path_to_dicoms>/95555-3-1.dcm

In the above commands, 95555-2-1.dcm and 95555-3-1.dcm represent the data within the same session? Because the directories, path_to_dicoms, were the same, I thought so. However, 2 or 3 in each 95555-2-1.dcm and 95555-3-1 might represent the session number. We can't understand which is right.

Please give me your suggestion. Thank you,

Kenta
