Here I am giving -lateral z (like for membrane simulations). Is it fine for
spherical systems also?



No. The system is a sphere, so what use is it to calculate motion perpendicular to z when you have lipids moving in all three spatial dimensions? A vesicle is very different from a membrane, in which the lipids move in a plane, thus making "-lateral z" useful.

Dear all,
I am simulating a spherical lipid vesicle. I want to calculate the
diffusion coefficient for each lipid component in 3D. How to calculate it
using g_msd (or any other tool like g_velacc)?

Thank you for your concern
