[Chimera-users] Inter-molecular H-bonds between water molecules not displayed in per-frame script

Know this has been a while, but just came back to it after a long while.
Got most of your suggestions working, but cannot get water-water hbonds
going. After some investigation, I think this could be due to the fact that
I'm using TIP4-EW water. Reason is that I got water-water hbonds working
with TIP3 and after trying lots of permutations cannot get this going.
My current per-frame script command for showing Hbonds is:
select :159-165.*; hbonds line 5 color gold selRestrict any reveal true;
setattr p color gold :159-165.*;
setattr g lineType 1
This works fine in that hbonds between water and protein/ligand residues
are shown, but none between the water which is a problem.
Any advice would be greatly appreciated. :)
