Is there a parameter that can be changed to control how "cartoon style modeH tube" draws a continuous helix? In my model, most of my helices are broken up into 2-4 discontinuous helices (especially the long, curved ones). 

In pymol (cylinders mode) and chimera (pipes and planks depiction), the same helices are drawn as a single, continuous helix, suggesting that my model is ok. I tried adding a HELIX definition in the pdb file, and also tried forcing chimeraX to draw a helix using the setattr command, but neither strategy has helped. I also tried playing with the dssp energyCutoff with no success.

Thanks,
