Hi all,

I selected my molecule and used writepdb to convert .coor to pdb file but
vmd is giving following error :-

PDB WRITE ERROR: Position, occupancy, or b-factor (beta) for atom 0
                                 cannot be written in PDB format.
                                 File will be truncated.

This has been discussed in mailing list :-

I shifted the origin to center of mass and set occupancy and beta to zero
according to answer in above link but still I am getting writepdb failed

Thanks in advance,
