The described here file formats for .rdf and .pot files are valid for MagiC v. 2.0 and higher. The format of files for .rdf and for potentials is similar and we give here a common description of it refering as "RDF/potential" file format.
The RDF/potential file consists of a header section, marked by tags &General
and &EndGeneral describing general properties of the RDFs/Potentials set for a
specific system, and independent RDF/potential records, marked
&Potential ... &EndPotential or &RDF ... &EndRDF respectively,
which specify RDF/potentials for each individual interaction. Each individual RDF/Potential
can be included to the RDF/potential file from a separate file by include statement.
Non-Bonded (NB) RDF/Potentials are identified by atom types involved in the RDF/Potential. Pairwise (B) and Angle-bending (A) bonds are identified by the molecular type they belongs to and the relative bond number in the molecular type. Each Potential can be protected from correction (Fixed) by specifying the flag Fixed=True in the corresponding section of the potential file. Such potentials do not change during the inverse procedure.
