[PyMOL] visualize autodock vina results

Dear pymol users,

I am visualizing autodock vina results using PyMOL:

I open out.pdbqt (containing 9 docked conformations of ligand)
I open pr.pdb (containing protein structure)

I want to have 1 pdb file containing one of conformations of ligand
(for example number 1 which is the best pose) + protein structure.
To this, I used following:

load out.pdbqt,obj1
load pr.pdb, obj2

split_states obj1

create obj3, (obj1_0001, obj2)

save obj3.pdb, obj3

In pymol, I see the following:

all
obj1
obj2
obj1_0001
obj1_0002
obj1_0003
obj1_0004
obj1_0005
obj1_0006
obj1_0007
obj1_0008
obj1_0009
obj3

After deactivating all except obj3, in obj3, I see protein + first state of
my ligand in pymol, but when I open obj3.pdb file using the text editor,
there as only END word. I want to use this obj3.pdb file as an input for
ligplot program.

What is the reason of this state?

Best,
Leila
