alexandra,

i was just able to load a molecule into pymol and set its tube radius to XYZ by doing the following:

hide everything
cartoon tube, all
show cartoon, all
set cartoon_tube_radius, XYZ

another thing which you can try if you want variable (residue-specific) tube thicknesses which are scaled by b-factor fields is to use the "putty" representation (try "cartoon putty, all" and then color by spectrum on b-factors).

disclaimer is that this was all in pymol v0.98 on linux... (i don't know about macpymol).

good luck,
cameron

Dear all,

Is there a way to adjust the cartoon tube thickness in Pymol? I have tried using cartoon_tube_radius but it does not seem to work. I am using MacPymol version 0.95.

Thank you very much in advance,
Alexandra
