+ | ===== Optionnal step: better list of g-vectors based on cif file ===== | ||
+ | |||
+ | In some cases (complex silicates with many peaks, multi-phase indexing, etc) it can be useful to have a better list of peaks in the g-vector file. This list should be calculated from a CIF file for the phase you will try to index. | ||
+ | |||
+ | The procedure is a bit tedious, as follow: | ||
+ | * Create a CIF file for the phase you are trying to index, with the proper unit cell parameters and atomic positions, | ||
+ | * Use the [[processing:list-peaks-from-cif|timelessPeaksFromCIF]] to generate a list of peaks, with h, k, l, intensity, ds, and 2theta | ||
