[gmx-users] Autocorrelation functions for distance vector

[Apramita Chand]

Dear All,
I want to calculate the time-dependent autocorrelation function for a
peptide's end-to-end distance vector . If I use g_dist , it gives me a
dist.xvg but though -lt option is there, the lifetime.xvg file is not
generated.
Is there any command to calculate the autocorrelation function? ( I am
using GROMACS version 4.6)


Regards,
Apramita
