I have a few questions regarding Sienax in FSL, which if you could possibly answer for me would be absolutely great:
1. In the Sienax Report, what units are the numbers given for 'pgrey Vol', 'pgrey unnormalised Vol', 'vcsf Vol', 'vcsf unnormalised Vol', 'GREY Vol', 'GREY unnormalised Vol', 'WHITE Vol', 'WHITE unnormalised Vol', 'Brain Vol' and 'Brain unnormalised Vol'?
2. What is the definition of normalised and unnormalised volumes according to FSL and how is normalisation achieved?
3. After extracting specific deep grey matter structures (hippocampus, thalamus, etc..) using FIRST, where can I find a number indicating the volume for this specific structure?
I would much appreciate your help
Thank you for your time
