+ | ===== Phase identification and peak fitting ===== | ||
+ | |||
+ | You can use [[https://github.com/seto77/PDIndexer|PDIndexer]] to identify your phases and fit their unit cell parameters. | ||
+ | |||
+ | To do so | ||
+ | * Remove the first line in the file (the header), | ||
+ | * Add a constant background to all intensity values. PDIndexer does not work if your diffraction intensities go to zero. This can be done in excel, for instance, | ||
+ | * Save the histogram with the new intensity values with an '.xy' extension, | ||
+ | * Open the XY file in PDIndexer. | ||
