I’ll make sure to include it in the ChimeraX implementation when I get there. To get ChimeraX where it needs to go I can’t put too much work into the current Chimera but nonetheless I added a “lineType” option to the hbonds/findhbonds command so that at least in the command version you can get dashed H-bonds without code modifications. The valid options for the lineType are: solid, dashed, dotted, dash-dot, and dash-dot-dot. The option will be available in the next daily build.

Great Eric, thanks. Works as advertised.

Any chance of making this more straightforward in ChimeraX or future Chimera releases?

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

To have all hydrogen bonds start out dashed, after line 991 of <your Chimera>/share/FindHBond/base.py (which should be “pbg.lineWidth = lineWidth”) add:

          pbg.lineType = chimera.Dash

with the same indentation as the preceding line. On a Mac, “<your Chimera>” will be Chimera.app/Contents/Resources.
