Re: [PyMOL] drawing a bond between the same Calpha atom in different states

Hey :) Can't resist the challenge... For any given ensemble, you can draw a trace through the C-alphas using the following lines, illustrated here for the NMR ensemble '1NMR': # Get the structure fetch 1nmr # Get the number of states n = cmd.count_states('1nmr') # Collect the C-alpha

Hi Jon, You also have to update the three numbers before. So to go from white to blue is cmd.load_cgo([i for j in x for u,v,f in zip(j,j[1:],range(n)) for i in [9.0]+u+v+[1.3, 1-(1.*f)/n,1-(1.*f)/n,1, 1-(1.+f)/n,1-(1.+f)/n,1 ]],trace) If you want to go from blue to white to red, it's

Hi All, I have 2 different states of the same molecule..different conformations generated from MD, so the same number of Calpha atoms, with a direct 1:1 mapping between Calphas with the same residue numbering. I would like to draw a bond between equivalent C-alpha atoms,
