On reading the input file CONFIG, DL_POLY_2 performs a check to ensure
that the atoms specified in the configuration provided are compatible
with the corresponding FIELD file. This message results if they are
not.
Action:
The possibility exists that one or both of the CONFIG or FIELD files
has incorrectly specified the atoms in the system. The user must
locate the ambiguity, using the data printed in the OUTPUT file as a
guide, and make the appropriate alteration.
