While executing gmx_mpi grompp command ionic liquid system I am getting the following warning.
WARNING 1 [file ETA_nonbonded.itp, line 5]:
Atomtype hn was defined previously (e.g. in the forcefield files), and
has now been defined again. This could happen e.g. if you would use a
self-contained molecule .itp file that duplicates or replaces the
contents of the standard force-field files. You should check the contents
of your files and remove such repetition. If you know you should override
the previous definition, then you could choose to suppress this warning
with -maxwarn.
WARNING 2 [file ETA_nonbonded.itp, line 6]:
Atomtype c3 was defined previously (e.g. in the forcefield files), and
has now been defined again. This could happen e.g. if you would use a
self-contained molecule .itp file that duplicates or replaces the
contents of the standard force-field files. You should check the contents
of your files and remove such repetition. If you know you should override
the previous definition, then you could choose to suppress this warning
with -maxwarn.
WARNING 3 [file ETA_nonbonded.itp, line 9]:
Atomtype h1 was defined previously (e.g. in the forcefield files), and
has now been defined again. This could happen e.g. if you would use a
self-contained molecule .itp file that duplicates or replaces the
contents of the standard force-field files. You should check the contents
of your files and remove such repetition. If you know you should override
the previous definition, then you could choose to suppress this warning
with -maxwarn.
Can this warning be ignored? Could anyone suggest how to resolve the problem?
