All model-free models script mode - the sample script

The sample script which demonstrates the optimisation of all model-free models from m0 to m9 of individual spins is model_free/ The important parts of the script are:

# Set the data pipe names (also the names of preset model-free models).
pipes = ['m0', 'm1', 'm2', 'm3', 'm4', 'm5', 'm6', 'm7', 'm8', 'm9']

# Loop over the pipes.
for name in pipes:
    # Create the data pipe.
    pipe.create(name, 'mf')
    # Set up the 15N spins.'noe.500.out', res_num_col=1)'N')
    spin.element(element='N', spin_id='@N')
    spin.isotope('15N', spin_id='@N')
    # Load a PDB file.
    # Load the relaxation data.'R1_600',  ri_type='R1',  frq=600.0*1e6, file='r1.600.out',  res_num_col=1, data_col=3, error_col=4)'R2_600',  ri_type='R2',  frq=600.0*1e6, file='r2.600.out',  res_num_col=1, data_col=3, error_col=4)'NOE_600', ri_type='NOE', frq=600.0*1e6, file='noe.600.out', res_num_col=1, data_col=3, error_col=4)'R1_500',  ri_type='R1',  frq=500.0*1e6, file='r1.500.out',  res_num_col=1, data_col=3, error_col=4)'R2_500',  ri_type='R2',  frq=500.0*1e6, file='r2.500.out',  res_num_col=1, data_col=3, error_col=4)'NOE_500', ri_type='NOE', frq=500.0*1e6, file='noe.500.out', res_num_col=1, data_col=3, error_col=4)
    # Set up the diffusion tensor.
    diffusion_tensor.init(1e-8, fixed=True)
    # Generate the 1H spins for the magnetic dipole-dipole relaxation interaction.
    # Define the magnetic dipole-dipole relaxation interaction.
    interatom.define(spin_id1='@N', spin_id2='@H', direct_bond=True)
    interatom.set_dist(spin_id1='@N', spin_id2='@H', ave_dist=1.02 * 1e-10)

    value.set(-172 * 1e-6, 'csa', spin_id='@N')
    # Select the model-free model.
    # Minimise.
    # Write the results.
    results.write(file='results', force=True)
