[gmx-users] g_hbond -contact option

[Erik Marklund]

If I'm not mistaken, g_dist deals with the center of mass of the two groups 
chosen, whilst g_hbond -contact is all about the distances of individual 
atoms of the two/one group(s). g_hbond -contact works just like g_hbond, 
except that it ignores the angle criterion for hydrogen bonds. You can also 
provide a second distance using the -r2 option, assuming a two step 
interaction process. I strongly suggest using the latest version of gromacs 
when using g_hbond -contact, since there were a bunch of bugfixes made not 
too long ago.
