Hello,

it seem to me that Chimera is not able to do H-bond analysis between
water molecules when TIP4P water model is used. Am I right or I overlooked something ?

Hi Marek,
I am not aware of any such problem.  Could you use Help->Report A Bug to send in a bug report, and provide more details about the problem you are having (what structure you used, what you did, what happened)?  Thanks!
