schrodinger.application.bioluminate.patch_utils.msurfext module

schrodinger.application.bioluminate.patch_utils.msurfext.erf_then_divide(x, constant)

smoothing function based on error function.

schrodinger.application.bioluminate.patch_utils.msurfext.ele_smoothing(distances)

charge smoothing routine. By default, we allow the charge to be visible over 10 Angstroms. Other distances may require some adjustments of the constants being used.

schrodinger.application.bioluminate.patch_utils.msurfext.lipo_smoothing(distances, rcut=5.0)

calculates the lipophilicity field along an exponential function on the basis of a distance cutoff

schrodinger.application.bioluminate.patch_utils.msurfext.smooth_grid_values(vertex_positions, atom_positions, atom_values, smooth_func='ele', rcutoff=10.0, verbose=False)

core function to smooth the surface grid values according to partial charge (‘ele’) or hydrophobicity (‘lipo’).

Parameters

• vertex_positions (np.array) – vertex positions (x,y,z) for each input value

• atom_positions (tuple) – atom positions, same format

• atom_values (tuple) – atom values

• smooth_func – smoothing function (valid entries are ‘lipo’, ‘ele’)

• rcutoff – distance cutoff for smooth_func
