You can run Fourier from a console as follows:
Local_Prompt> fourier [input_file] <cr>
Input_File is the code of the input file summarizing the instructions for running Fourier.
Also you need a file containing the hkl’s and structure factors. The extension for both files are inp and fou respectively. If Fourier runs properly il will output up to two files:
CODE.fout General output file
CODE.bin Binary file containing the electron (or scattering) density inside the unit cell.
