I am confused by your question.<br>
<br>
I can't tell what is happening with the structure in the first (top) ribbon/stick image that you sent without having the data (e.g. a session).<br>
<br>
In the bottom three images you sent, with the details of what you did, the last image shows H-bonds in the graphics window and in the Reply Log. So there is no problem for those, right? The only strange thing is that in the Model Panel image there are four lines for "combination" model #1 when I would expect only one. You should probably close the original models and the extra combination models so that you only have one "combination" model when you do the H-bonds calculation.<br>
<br>
For the structure in the first (top) image, the only ideas I have are<br>
(1) maybe you did not make it into a combination model. I.e. if the ligand is 0.1 and the receptor is 0.2, it will not find the H-bonds between them.<br>
(2) maybe there really aren't any H-bonds. You could try increasing the "Relax" values if you think there are H-bonds but the distances are slightly too long or the angles are not optimal for H-bonding.<br>
<br>
I hope this helps,<br>
Elaine<br>
