How to select the best model as input for CASSCF calculation?
Calculate the D for each complex separately from two CASSCF calculations. D is a local property. You can though simulate any magnetic data by combining two D values by fitting.
How can I use the cif data obtained from rietveld refinement extracted via gsas2, for microstructural analysis using ETEX software?

I like PCW and profex as they are free softwares. It would be great to put the cif, and str files together with my samples to better identify. I work with XRD applied to mineralogy. Thanks!
