I'd have some questions about g_hbond in Gromacs-3.2.1. I'm using this tool
with trajectories already examinated with g_hbond in Gromacs-2.1.4.
1) Why does the AC function become negative at high times?
2) What is exactly the meaning of the parameter defined by the option
-max_h and when should I have to use it?
3) What are the values given in the third column of the file obtained with
I supposed the exponential fit of the AC function, but it doesn't seem so
with my data.
I tried to use the option -shell with -dan, but the file defined in -dan
was not written, though it was reported in the output of g_hbond. (In the
preceeding Gromacs version I used -da with no problem).
Thanks in advance for any help.
