Inputs:

• File with reflection data (Fobs or Iobs), and R-free flags (optionally);
• label(s) selecting which reflection data arrays should be used (in case there are multiple choices in input file, there is no need to provide labels otherwise);
• PDB file with input model;
• some other optional parameters.

Usage examples:

1. phenix.model_vs_data model.pdb data.hkl
2. phenix.model_vs_data model.pdb data.hkl f_obs_label="F" r_free_flags_label="FREE"
3. phenix.model_vs_data model.pdb data.hkl scattering_table=neutron
4. phenix.model_vs_data model.pdb data.hkl twin_law='h,-k,l+h'

Default parameters:

• f_obs_label = None
• r_free_flags_label = None
• scattering_table = wk1995 it1992 *n_gaussian neutron
• high_resolution = None
• twin_law = None
• n_bins = 20
