Hi,

We do not recommend this option. It is really only there for people who want to use an alternative version of the FMRIB58_FA template.
> 2. If selecting -T in 2nd step , then must I use -T in 3nd step ?
No. The recommendation (as stated in the help) is -T for stage 2 and -S for stage 3.
> Or if selecting -n in 2nd step , then must I use -S in 3nd step?
This would be the recommendation.
> Is there a connection between them? I don't think so . And you ?
They are pretty much separate, although using -t and then -T doesn't really make sense.
> 3. How should I choose these parameters ?
I would follow the recommendations, as they are there for a reason.
All the best,
Mark
