[Chimera-users] Ca-Ca difference plot

[Luca Pellegrini]

Hi,

I have superimposed two structures of the same protein in two different conformations, and now I would like to calculate a plot of the distances between alpha carbons for each residue in the two conformations, to quantify the relative movement of different domains in the protein structure. Can anyone please explain a simple way of doing this in Chimera?  Apologies if I missed something obvious, I tried 'RR distance maps' but couldn’t figure out how to do this simple task. 

Best regards,
Luca
