[gmx-users] Occupancy warning

[Zhiguo Liu]

Dear gmx-users ，
     When I did pdb2gmx to my homology protein models, I always received the warning
  "  
  WARNING: there were 620 atoms with zero occupancy and 0 atoms with
         occupancy unequal to one (out of 2139 atoms). Check your pdb file.
  "
Do I always have to check my pdb file to get rid of this warning message? I don't want to optimize my structure too much, for this may change some essential features from the template protein. Or I can just leave it alone?

Best Regard!
