Scaling#
MTZ IO#
ess.nmx has MTZ IO helper functions. They can be used as providers in a workflow of scaling routine.
They are wrapping MTZ IO functions of gemmi.

Build Pipeline#
Scaling routine includes:
Reducing individual MTZ dataset
Merging MTZ dataset
Reducing merged MTZ dataset
These operations are done on pandas dataframe as recommended in gemmi. And multiple MTZ files are expected, so we need to use sciline.ParamTable.

Change Provider#
Here is an example of how to insert different filter function.
In this example, we will swap a provider that filters EstimatedScaledIntensities and provide FilteredEstimatedScaledIntensities.
After updating the providers, you can go back to Compute Desired Type and start over.
