[gmx-users] RE: missing atom

[Subramaniam Boopathi]

Hello All


                   I have created a nwe residue "NIC" in AMBER 03
Forcrfield and I have added corresponding data to the aminoacid.rtp  In the
aminoacid.rtp,  I have added all atoms topology information then I type the
command


                         * ./pdb2gmx_d -f abnic.pdb -o abnic.gro -p
abnic.top -ignh
*

but it told me some atoms are missing


                 atom HAQ is missing in residue NIC 8 in the pdb file
         You might need to add atom HAQ to the hydrogen database of
building block NIC
         in the file aminoacids.hdb (see the manual)

  can yopu please help me to overcome this problem. I am a buddy stage to
learn GROMACS.
