Then, how to mention the direction for spherical particles Sir?
Read g_msd -h again, paying specific attention to the -type flag.

Thank you sir for the prompt reply.

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
