Hey all,
just the other day I discovered a nifty command in pymol.
rms_cur selection1, selection2
determines the deviation between two (previously aligned) selections
without doing a fit. Here's what I do:
rms_cur (object1 and i. 20:29 and (name c,o,n,ca)), (object2 and i.
30:39 and (name c,o,n,ca))
Hmmm, doesn't work. Error:
ExecutiveRMS-Error: No atoms selected.
OK, differnt try (debugging for beginners):
select selection1, (object1 and i. 20:29 and (name c,o,n,ca))
So far so good. Feedback:
Selector: selection "selection1" defined with 40 atoms.
And again:
select selection2, (object2 and i. 30:39 and (name c,o,n,ca))
Good again. Feedback:
Selector: selection "selection1" defined with 40 atoms.
Now I go for gold:
rms_cur selection1, selection2
Arrgh, bummer:
ExecutiveRMS-Error: No atoms selected.
What am I doing wrong?? I'm using pymol 0.95 under WinXPpro and pymol
0.95rh9 under linux/FC2.
