I would like to modify the g_hbond code (or preferably, know how to implement g_hbond if it is already capable) to count the number of non-hydrogen bound water OH donors in a simulation. I define a non-hydrogen bound donor as one that does not meet the distance requirement, or one that may meet the distance requirement for a hydrogen bond, but does not meet the angle requirement.
An inferred value of non-hydrogen bound OH donors is not exact because there is not a rigorously defined maximum value for the number of hydrogen bonds per water, (e.g. a single OH donor may qualify as part of a hydrogen bond at two adjacent water's O-acceptor sites, making the maximum possible number of hydrogen bonds for the water of this particular OH donor greater than 4). Is there a way to implement g_hbond to do this? If not, any specific information on what to consider, and how to modify the g_hbond source code to count non-hydrogen bound water OH donors is greatly appreciated. Robin -- Robin C.
