sorry for perpetuating confusion :-)  when I visualize hbonds with
'hbonds 0.1' they are white.  if I color hbonds by type, the 'default'
color is yellow.  I am advocating consistency between these two defaults
- and I suggest white since it is the cpk color for hydrogen.




Is that using Chime with a PDB file? My experience is different. With Chime I get half-colored CPK color of donor, half acceptor (blue/red for NH/O) as default. (Aside--I don't know which is properly called the donor--the one with the H or the one with the pair of electrons.)


This is also true with my version of Raswin (2.6).

So from what I can see, the default is a H-bond that has the colors of the two end atoms. This is before or after "hbonds 0.1" then when I type "color hbonds type" I get the expected colors based on the chain offsets between the two end points. Tim, maybe the protein you are looking at has only long-distance (yellow) H bonds.

and there should be no code-level distinction between protein and
nucleic hydrogen bonds - one can easily build selections to tweak
those apart.

and in fact, I retract my own statement here.  see my recent email to
the list responding to Bob's comments.


my day, my life, is a work in progress. please excuse the mess. :-)


regards,

tim
