A summary of all input and output files is given below:

Filename	File type	Function
file1.inp	Input	Contains information about total number of paramagnetic centres and the Hamiltonian specifying the relationship between various metal centres.
file2	Input	Contains spin densities on the paramagnetic centres in different spin states and the energy of the corresponding states.
file1_form.out/file_spin.out	Output	Contains information about the calculated coupling constants.
bigg	Output	Contains information about sets of equations that yield J-values > 50 cm-1.
singul	Output	Contains information about sets of equations that are singular and is produced by ej_calc_form. This file is required for the proper execution of the executable ej_calc.
nrg_frm_jval_form/nrg_frm_jval	Output	Contains the approximate energy of the all possible 20.5x states (x = number of paramagnetic centres).
