[gmx-users] viscosity and acflen in g_energy

[Vitaly V. Chaban]

Hi,

When using g_energy to calculate viscosity ("g_energy -vis"), in
enecorr.xvg the ACF of stress tensor is output. How can one specify
the "acflen" of this ACF?
I try the key "g_energy -vis -acflen XXX" but the length of the ACF is
still equal to the half of the trajectory length.

Thanks,
Vitaly
