Hallo, I have an annoying problem. I have pdb file with Na+ atoms defined as
ATOM 1 Na+ Na+ 53 -1.106 7.854 52.244 1.00 0.00 Na ATOM 2 Na+ Na+ 54 -0.106 3.854 27.244 1.00 0.00 Na ATOM 3 Na+ Na+ 55 1.894 -6.146 62.244 1.00 0.00 Na ATOM 4 Na+ Na+ 56 8.894 -5.146 42.244 1.00 0.00 Na ATOM 5 Na+ Na+ 57 -4.106 4.854 13.244 1.00 0.00 Na ATOM 6 Na+ Na+ 58 -10.106 -6.146 42.244 1.00 0.00 Na ATOM 7 Na+ Na+ 59 -7.106 5.854 35.244 1.00 0.00 Na ATOM 8 Na+ Na+ 60 4.894 4.854 49.244 1.00 0.00 Na ATOM 9 Na+ Na+ 61 9.894 -3.146 22.244 1.00 0.00 Na now if want to select these Na+ with PyMOL>select n. na+ Selector: selection "sele" defined with 0 atoms. Any ideas how to select them? I tried renaming them to Na and then select n. na which works. So I assume the problem is "+" which is used for add in pymol. I also tried n. "na+" which did not work either. thanks in advance, Abhi.
