Parameters:

ax_list – List of matplotlib.axes.Axes or None if a new figure should be created.

Return: matplotlib Figure.

Keyword arguments controlling the display of the figure:

kwargs	Meaning
title	Title of the plot (Default: None).
show	True to show the figure (default: True).
savefig	“abc.png” or “abc.eps” to save the figure to a file.
size_kwargs	Dictionary with options passed to fig.set_size_inches e.g. size_kwargs=dict(w=3, h=4)
tight_layout	True to call fig.tight_layout (default: False)
ax_grid	True (False) to add (remove) grid from all axes in fig. Default: None i.e. fig is left unchanged.
ax_annotate	Add labels to subplots e.g. (a), (b). Default: False
fig_close	Close figure. Default: False.
plotly	Try to convert mpl figure to plotly.

plot_atomic_levels(ax_list=None, fontsize: int = 8, **kwargs) → Any

Plot atomic levels in Ha for all pseudos.

Parameters:

ax_list – List of matplotlib.axes.Axes or None if a new figure should be created.

Return: matplotlib Figure.

Keyword arguments controlling the display of the figure:

kwargs	Meaning
title	Title of the plot (Default: None).
show	True to show the figure (default: True).
savefig	“abc.png” or “abc.eps” to save the figure to a file.
size_kwargs	Dictionary with options passed to fig.set_size_inches e.g. size_kwargs=dict(w=3, h=4)
tight_layout	True to call fig.tight_layout (default: False)

ax_annotate	Add labels to subplots e.g. (a), (b). Default: False
fig_close	Close figure. Default: False.
plotly	Try to convert mpl figure to plotly.

yield_figs(**kwargs)

Generate a predefined list of matplotlib figures with minimal input from the user.

write_notebook(nbpath=None)

Write a jupyter notebook to nbpath. If nbpath is None, a temporay file is created. Return path to the notebook. A typical template:

# Preable.
nbformat, nbv, nb = self.get_nbformat_nbv_nb(title=None)

#####################
# Put your code here
nb.cells.extend([
    nbv.new_markdown_cell("# This is a markdown cell"),
    nbv.new_code_cell("a = 1"),
])
#####################

# Call _write_nb_nbpath
return self._write_nb_nbpath(nb, nbpath)

abipy.ppcodes.oncv_plotter.psp8_get_densities(path, fc_file=None, ae_file=None, plot=False)

Extract AE-core, AE-valence and PS-valence from a psp8 file. Optionally write .fc and .AE file in format suitable for AIM and cut3d Hirshfeld code.

Parameters:

• path – path of the psp8 file

• fc_file – File-like object to .fc. and .AE file Set to None if files are now wanted.

• ae_file – File-like object to .fc. and .AE file Set to None if files are now wanted.

• plot – If true, call matplotlib to plot densities.

Returns:

(rmesh, psval, aeval, aecore)

Densities are multiplied by 4 pi i.e. int aecore * r**2 dr ~= N_core

Return type:

namedtuple with numpy arrays

Warning

The densities do not integrate exactly to the number of core/valence electrons. in particular the valence charge in elements with large Z as valence electrons are more delocalized and the finite radial mesh does not capture the contribution due to the tail. Client code is responsible for extrapolating the valence charge if needed. The error in the integral of the core charge is usually much smaller and should be ok for qualitative analysis.

ppgen Module

Interface for pseudopotential generators.

class abipy.ppcodes.ppgen.Status

Bases: int

An integer representing the status of the ‘PseudoGenerator`.

classmethod as_status(obj: Status | str) → Status

Convert obj into Status.

classmethod from_string(s: str) → Status

Return an instance from its string representation.

class abipy.ppcodes.ppgen.OncvGenerator(input_str: str, calc_type: str, use_mgga: bool, workdir: str | None = None)

Bases: _PseudoGenerator

This object receives an input file for oncvpsp, a string that defines the type of calculation (scalar-relativistic, …) runs the code in a temporary directory and provides methods to validate/analyze/plot the final results.

retcode

Retcode of oncvpsp

classmethod from_file(path: str, calc_type: str, use_mgga: bool, workdir: str | None = None) → OncvGenerator

Build the object from a file containing the input parameters.

check_status()

Check the status of the run, set and return self.status attribute.
