loicbd Hi everyone, I’m using a macro originally written by Lynne McCusker to generate input files for Fourier maps in Superflip (https://topas.awh.durham.ac.uk/doku.php?id=fourier_maps). Up until now, I worked with X-ray data, but I’m now working with neutron diffraction. Do I need to modify anything in the macro to ensure that neutron scattering lengths / cross sections are used ?

leiw Actually, in the inp codes for the neutron diffraction, the Fourier map can be directly viewed by the implemented fourier_map_formula in the Topas software.
