Hi Justin,

It is which part in the force field. Exactly which file I have to look to
overcome this errors.


Go to the line number in the .top indicated in the error message and determine the atom types. This will tell you the sequence of atom types involved in the R-B dihedral that is missing. In theory, you would then add missing parameters to ffbonded.itp, if they exist.

Hi Justin,

This is another type of error while running energy minimization:
what to do for these type of errors.


They're exactly the same as the dihedral error from before.  You're using
parameters that don't exist in the force field.

  Hi Justin,

I included 1 DMPC molecule parameters in the file should I need to
include
128 molecules parameters in the file .rtp.


  No.  Residue definitions are used any time they are encountered in the
coordinate file.  There is no need for such redundancy at the force field
level.
