Hi,
This is my fault. Unfortunately this is the rare case where the manual
was updated and not the release branch of the code. This functionality
does exist and should have been in the release, but as you have
correctly pointed out it is not.
I will look into developing a patch that will put this functionality
into the AT12 version of cpptraj. Right now there is another patch
under development, so I may have to wait until after that is released.
In the meantime, ptraj does have the ability to look at solvent-solute
hydrogen bonds and will print information on bridging waters.
My apologies for the inconvenience.
