Dear FSL experts,
I recently used the command run_first_all to obtain the subcortical structures. However, since I am doing analysis on multiple subjects and each subject has different size of brain. Unlike SIENAX which normalizes its outputs automatically, in order to get a normalized volume of the subcortical structures, I need to normalize the outputs of the FIRST. My question is that what i should do in order to normalize the output of FIRST to get a normalized volume of the subcortical regions?
Sincerely,
Tao
