FOD function recreation in MATLAB

Hello, I am trying to recreate voxel specific FOD functions in MATLAB. Are the 45 coefficients stored for the even spherical harmonics ordered for Y(0,0), Y(-2,2), Y(-1,2), Y(0,2), Y(1,2), Y(2,2), Y(-4,4), Y(-3,4) etc.? Also just to make sure, are the only spherical harmonics used even harmonics?

Thanks! Hank

Correct on both counts. You’ll find all this documented in detail on this page.
All the best,
Donald.
