Hi,

You need to use the 'include_ep' keyword when writing your PDB file, e.g.

trajin mytraj.nc
trajout mypdb.pdb include_ep

> I found the generating *.pdb file just have 3 atoms coordinates like O H1 H2, which is differ from the TIP4PFB model file with O H1 H2 EP 4 atoms coordinates. But I want the pdb file with4 atoms coordinates. So is there any command i do not kown for this in capptraj module, just not use python or fortran by myself.
