Hello I have problem in lammps with fix ave/correlate because is

correlation function is for global variables, i need correlation function

per atom

atom as incoherent/self-intermediate scattering function and velocity

auto-correlation function in order of 0.1 microseconds because dynamics of

supercooled liquids is very slow, i use FFT by calculation correlation

function but dump file by post-processing is very large 1T and read the

dump file is most time of calculation the correlation function, algorithm

use to calculation the correlation function on fly and have some ideas to

modify the code.

I hope your help

thank you very much

Bye

Samuel
