The FA values were averaged over multiple measurements during optimization processes. The p values are based on the t-test in which the FA values with different acquisition schemes were compared.

A,B,C,D,E,F,G, and H indicate different acquisition conditions.

FA= Fractional Anisotropy

DGED= diffusion gradient encoding directions

p values=student’s t-test among different acquisition conditions, for example, p=0.04409 between A and B
