Beginning from pymol 0.98, there is a new function called “sequence mode”
You can just click the pymol Tcl/Tk GUI toolbar [DISPLAY] -> [SEQUENCE] to enable the sequence mode, then you will see a sequence of you PDB file in the PyMOL viewer window. Seqeunce mode is a very powerful advantage, because you can use mose left button to select residues you have interests, then pymol automatically generetes a selection object for you, like what I show in this figure, I load 1PJW.pdb, enable the NMR ensemble structure view (set all_states, on), then enable the sequence mode, and select residues 21~ 37 quickly. The viewer window shows many purple dots which are the residues I selected.
See how amazning convenience the function is!
