Cppxfel Statistics

There are a number of merging statistics and plots hwich can be generated using cppxfel and your favourite graph-drawing software. cppxfel has a number of commands which generate CSV files which can be plotted elsewhere.

Correlation between two images

cppxfel can be used to generate plots of intensities between two images. To calculate the correlation between two halves of the data set in the first merge:

cppxfel.run -cc half1Merge0.mtz half2Merge0.mtz

This creates a new CSV file named correlation.csv The "first intensity" and "second intensity" columns can be plotted in a suitable program (e.g. R, Veusz, etc.).

Test

This can also be carried out for individual images...
