Hi Yeping, the spectrum command has a "byres" argument to operate on the residue level:
PyMOL>spectrum b, blue_white_red, byres=1 There is no white_blue color ramp, but there is a script which provides this: http://pymolwiki.org/index.php/Spectrumany It doesn't have the byres argument. If you only show cartoon, just limit the selection to CA atoms: PyMOL>run path/to/spectrumany.py PyMOL>spectrumany b, white blue, name CA If you want to show all atoms, you can map the CA atom b-factor to all residue atoms with this script: http://pymolwiki.org/index.php/AlphaToAll Hope that helps.
