[gmx-users] Re: coarse grain hydrogen bonding

To detect a hydrogen bond in a conventional sense using geometric criteria, you 
need an atomistic representation.  There are tools available to reconstruct 
atomic positions from CG models, but I have never used them so I will not 
comment further other than to suggest you may want to investigate them.  Of 
course, that leaves open for debate whether or not the hydrogen bond would 
actually be there or if it is caused solely by the reconstruction algorithm.

My sense is that no, there isn't a very easy way to collect hydrogen bonding 
data from a CG trajectory.
