Hello everyone,

the pdb file for which I want to create psf file contains PO4 residue ..
when i run the script to create the psf file..it gives an error
Unknown residue PO4..

i checked in the topology file for PO4 residue... there is only entry for
atoms of PO4...how do i include them in the psf file...
or is there any pdblias for PO4 resdue...

the part of the pdb file is pasted here:
HETATM 4432 P PO4 B 147 5.931 -21.573 3.319 1.00 32.97

thank you
