[Chimera-users] Preference/default for H-bond representation

Hi Markus,
Although there is something like that for distance monitors (Save button in the Distances tool), unfortunately there isn’t for H-bond pseudobonds, nor is there an option in the findhbond command or dialog to make them dashed in the first place.

That leaves changing them after the fact, e.g. the following command would make all pseudobonds dashed:

setattr g lineType 2

You can also specify subsets but only by endpoint atoms, not by the pseudobond group name.

GUI ways to make them dashed:

(A) Pseudobond Panel (under Tools… General Controls), choose “hydrogen bonds” and click “attributes…” on the right, and in the attributes dialog change “line style”
- OR -
(B) select any H-bond pseudobond, click green magnifying glass icon to open Selection Inspector, Inspect: pseudobond group, change “line style”

How I know to use”setattr” command “g” (pseudobond group” and the attribute name “lineType” and its possible values are by seeing in either of the above dialogs that it is a pseudobond group attribute, and then mousing over “line type” in the dialog to show balloon help with the attribute name and possible values.

There must be some place in the code to change it to always dashed, but somebody else would have to advise on that...

Sorry for the inconvenience,
Elaine
