I would like to segment gray/white matter of the cerebellum by using FIRST.
Following the FSL webpage, procedures are, I suppose, as follows;
('Subject1' is a T1 image.)
first_flirt Subject1 Subject1_to_std_sub -cort
run_first -i Subject1 -t Subject1_to_std_sub_cort.mat -n 40 -o Subject1_R_Cereb -m
first_boundary_corr -s Subject1_R_Cereb -i Subject1 -b none -o
Are those procedures appropriate for segmentation of the cerebellum?
1. What are suitable number of modes in /run_first/ (Is 40 suitable)?
2. Which is adequate option for -b in /first_boundary_corr/ (fast, thresh, none)?
I would appreciate it very much if anyone could give me comments on this issue.
