The parameter file

The performance of the program can be determined with the settings in a parameter file. The parameter file can be edited by writing in an ASCII file by hand or by using the GUI. A commented default file can be created automatically in the present working directory using the cora_inp program. If no file is supplied cora_inp will be launched automatically, so for the first run one does not need to bother about it. Some parameters depend on the what kind of spectrum is going to be analyzed (e.g., start values for line widths), so cora_inp needs a spectrum to be provided. Detail description of each parameter can be found in Sect. 6.
Cora can be started without specifying an input file, it is then automatically generated and named fit.inp (in the current working directory).
