[Chimera-users] Curves+ graphics of DNA

[Richard LAVERY]

I am trying to visualize the graphic output from the Curves+ of a DNA duplex, which consists of two smooth backbone traces linked by vectors indicating the measured widths of the minor and major grooves. In the test case shown, adding two atoms defining one such vector and a single CONECT line linking them together (see attached PDB file) leads to three new bond vectors in the representation shown below. Am I making a mistake, or is this a problem with Chimera?
