Hello VMD users,

I found something a bit odd using the hbonds plugin. According to the plugin, the criteria for the formation of a hydrogen bond are the distance between the donor D and the acceptor A and the angle D-H-A. The cut-off angle is by default 20 degrees, which means that D and A are too close to each other. In my opinion, it should be the angle H-D-A with a cut-off angle of 20 degrees. What do you think ?

Thank you in advance,
