Note that this will cause you to only get hydrogen bonds for which water is an
acceptor; to get all hydrogen bonds, just use the default "SOL" group.

It should start right away...

For simply counting hydrogen bonds, there's really nothing special to do, as
long as the default criteria are reasonable in your judgment (they usually are).

I fixed the link.
