Hi All,
I used autodock to dock my ligand on macromolecule. So i finally get a
ligand docked structure. So I try to make a combine the pdbs. So I just
paste my docked ligand pdb file with the initial macromolecule pdb file and
I get a combined docked structure which seems to open well with VMD.
This is how my combined pdb looks like

................................. till 36
So, I just renamed the capital letter atoms in my original pdb to
small *corresponding
to mol2* (in brown) i got from antechamber .. as shown below
ATOM 1 ca parm99 1 -4.025 -3.449 2.287 0.00 0.00 p1

ATOM 13 C36 RES d 1 -4.473 -4.214 -3.604 0.00 0.00 p1
C
.. here i have renamed till 6 atoms to demonstrate .. in my pdb i did that
for all 36 corresponding atoms
Maybe the whole renaming procedure I am following is wrong. Basically, I
just want to load my combined macro_ligand.pdb using loadpdb without any
errors. I don't know if there is any standard way of doing that.
Thank you very much for the earlier responses. I am again sorry, if I
couldn't phrase my question well earlier.
Regards,
Jagdeesh
