[gmx-users] Error in system_inflate.gro coordinates does not match

[RINU KHATTRI]

hello every one
ohk i havbben pasted UNK portion from old files because it is still missing
in system.gro now after running minimization i got new error old problem
has resolved
                     :-)  grompp  (-:

-time        real   -1      Take frame at or first after this time.
-[no]rmvsbds bool   yes     Remove constant bonded interactions with virtual
                            sites
-maxwarn     int    2       Number of allowed warnings during input

-[no]zero    bool   no      Set parameters for bonded interactions without
                            defaults to zero instead of generating an error

                            atomtypes


Back Off! I just backed up mdout.mdp to ./#mdout.mdp.8#
Generated 813 of the 2346 non-bonded parameter combinations

ERROR 1 [file topol.top, line 22752]:
  No default Proper Dih. types

Excluding 3 bonded neighbours molecule type 'Protein_chain_A'
Excluding 3 bonded neighbours molecule type 'UNK'
Excluding 3 bonded neighbours molecule type 'POPC'

NOTE 1 [file topol.top, line 24831]:
  System has non-zero total charge: 14.788998
  Total charge should normally be an integer. See
  http://www.gromacs.org/Documentation/Floating_Point_Arithmetic
  for discussion on how close it should be to an integer.
