[gmx-users] g_hbond gromacs 3.2

[Ilya Chorny]

Hi david,
 
I have a couple questions about g_hbond. I noticed an Oct 2003  post
where you mention completely rewriting g_hbond.
 
Is the second column in the -ac output a fit to the first column? 
 
Also I noticed that when I use -noda and reduce the -r  value to .25  it
doesn't work. 
It gives me the same output as if I didn't use the -noda option. I then
compared my results using g_hbond_3.1.4 (r .25) and g_hbond (r .35) and
got 
very different results. The version 3.2 C(t) decays slower. My system is
a solute in  a box of solvent molecules. Since I can't use the -noda
option I can't make a direct 
comparison. Any help would be greatly appreciated.
 
Thanks
 
Ilya
