Dear all,


   When I generated the amber99sb force filed topology of a DNA molecule with gmx, a error code appeared: "Atom P in residue DA 1 was not found in rtp entry DA5 with 30 atoms". I tried to fix this but found there was no P atoms in all the 5' nucleic acid residues in dna.rtp.
   Can some one help me with this ?
