Dear gmx-users,

   I have met some problems in running pdb2gmx_d command..the information given by computer was listed as following. Who can tell me what happened in my operations?


Reading test.pdb...
Read 'pptemp.pdb', 259 atoms
Opening library file /usr/local/gromacs/share/top/xlateat.dat
13 out of 13 lines of xlateat.dat converted succesfully
Opening library file /usr/local/gromacs/share/top/aminoacids.dat
Analyzing pdb file
There are 2 chains and 0 blocks of water and 7 residues with 259 atoms

  chain  #res #atoms
  1 '1'     1      6  
  2 '2'     7    253  

WARNING: there were 8 atoms with zero occupancy and 251 atoms with
         occupancy unequal to one (out of 259 atoms). Check your pdb file.

 2: GROMOS96 43a1 Forcefield (official distribution)
 3: GROMOS96 43b1 Vacuum Forcefield (official distribution)
