CHANGELOG.md

v4.6.0

This minor release provides several improvements and bug fixes, mostly related to the HubbardStructureData and XPS/XAS calculations.

Since there were no changes in the schema for Quantum ESPRESSO v7.3, versions 4.3 and above of the plugin package should now also fully support the new Quantum ESPRESSO release.

👌 Improvements

• XAS: Enable Correct Parsing of Hubbard and Magnetic Data [f439504]
• PhCalculation: add symmetry related exit codes [5a6529f]
• seekpath_structure_analysis: HubbardStructureData compatibility [9cb1cfa]
• HubbardStructureData: add compatibility for <3D structures [d645069]
• HubbardStructureData: Add validation on site indices [960a371]

🐛 Bug fixes

• PwBandsWorkChain: Respect bands_kpoints in overrides [ae7d248]

• Fix inputs for molecules in the XPS calculation [b7f17cf]

🧪 Tests

• CLI: Add test for data structure import [5c3c301]

v4.5.1

This patch release fixes some issues with the changes introduced in b9c7517 and released in v4.5.0. The new approach for setting the q-points was unfortunately broken, which is now fixed in c353cc2. Moreover, the validation that was added to the top-level inputs of the PhBaseWorkChain requires the user to specify either the qpoints or qpoints_distance input. This means that work chains which wrap the PhBaseWorkChain but provide the q-points on the fly will have to disable this validation by setting the corresponding validator to None in the input spec. To avoid this, we have the validator check if one of the qpoints or qpoints_distance ports are still present in the port namespace. If not, the validation is skipped.

Higher-level work chains that wrap the PhBaseWorkChain can then simply exclude these ports when exposing the inputs:

    class WrapPhBaseWorkChain(WorkChain):
        """Example work chain that wraps a ``PhBaseWorkChain`` excluding q-points inputs."""

        @classmethod
        def define(cls, spec):
            super().define(spec)
            spec.expose_inputs(PhBaseWorkChain, exclude=('qpoints', 'qpoints_distance'))

👌 Improvements

• PhBaseWorkChain: skip q-points validation if ports are excluded [32536e8]

🐛 Bug fixes

• PhBaseWorkChain: fix set_qpoints step [c353cc2]

📚 Documentation

• CHANGELOG.md: improve release notes for v4.5.0 [b659625]

v4.5.0

Besides several bug fixes and documentation improvements, this minor release introduces some changes to the PhBaseWorkChain and how it is used. Most importantly, q-points are no longer defined directly on the PhCalculation in the ph namespace, but as a top-level input on the PhBaseWorkChain, either as a KpointsData node (see b9c7517):

ph_base_builder = PhBaseWorkChain.get_builder()

qpoints = orm.KpointsData()
qpoints.set_kpoints_mesh([2, 2, 2])

ph_base_builder.qpoints = qpoints

Or a qpoints_distance, which defines a linear density that can be used in combination with the structure to generate a mesh on the fly:

ph_base_builder = PhBaseWorkChain.get_builder()

ph_base_builder.qpoints_distance = orm.Float(0.3)

The protocols are also updated to use the new qpoints_distance input, with some reasonable default for the various options.

⚠️ Important: While the current defaults are reasonable, they by no means represent a rigorously tested protocol that guarantees a certain level of convergence. Be sure to run your own tests!

The get_builder_from_protocol() method of the PhBaseWorkChain now also recognises the electronic_type input argument. For example, when running an insulator, one can obtain a fully populated builder via:

from aiida_quantumespresso.common.types import ElectronicType

builder = PhBaseWorkChain.get_builder_from_protocol(
    code=ph_code,
    parent_folder=pw_remote_folder,
    electronic_type=ElectronicType.INSULATOR
)

which will set INPUTPH.epsil to True in the ph.x input file.

This release also bumps the default SSSP version in the protocols up to v1.3 (still using the PBEsol functional). In case you have not installed this newer version, you can do so with aiida-pseudo (version >=1.1.0):

aiida-pseudo install sssp -v 1.3 -x PBEsol

v4.4.0

This minor release mainly includes documentation changes, but also a small breaking change in [a389629]. Work chains that wrap the PwBaseWorkChain for an nscf or bands calculation and add the parent_folder during runtime would have to adapt the validator for the pw name space as follows to avoid warnings:

    spec.inputs['nscf']['pw'].validator = PwCalculation.validate_inputs_base

Now, the validator that checks for the presence of the parent_folder in the inputs is adapted so it checks if the parent_folder port is in the name space. If not, the validation is skipped. So work chains that wrap the PwBaseWorkChain to run an nscf or bands calculation can simply exclude the parent_folder port in the pw name space:

    spec.expose_inputs(
        PwBaseWorkChain,
        namespace='nscf',
        exclude=('clean_workdir', 'pw.structure', 'pw.parent_folder'),
        namespace_options={
            'help': 'Inputs for the `PwBaseWorkChain` of the `nscf` calculation.',
            'validator': validate_nscf
        }
    )

A new calculation function create_magnetic_configuration is added, which can be used to create a new StructureData with the required kinds for a specific magnetic configuration. For example, for an HCP structure with two Co sites:

In [1]: from aiida import orm

In [2]: from ase.build import bulk
   ...: structure = orm.StructureData(ase=bulk('Co', 'hcp', 2.5, 4.06))

The create_magnetic_configuration can be used to quickly create a new StructureData with two different kinds:

In [3]: from aiida_quantumespresso.calculations.functions.create_magnetic_configuration import create_magnetic_configuration
   ...:
   ...: results = create_magnetic_configuration(structure, [-2, 2])

In [4]: results['structure'].sites
Out[4]:
[<Site: kind name 'Co0' @ -2.7755575615629e-17,1.4433756729741,2.03>,
 <Site: kind name 'Co1' @ 0.0,0.0,0.0>]

In [5]: results['magnetic_moments'].get_dict()
Out[5]: {'Co0': 2, 'Co1': -2}

For more information, see the tutorial on how to work with magnetic systems:

https://aiida-quantumespresso.readthedocs.io/en/latest/tutorials/magnetism.html

The release also makes an important change in the dependencies related to a bug introduced in pydantic, see:

pydantic/pydantic#5821

Hence the version of pydantic is adapted to 1.10.8, where this bug is fixed.

v4.3.0

Release version 4.3.0 comes with a lot of new features, improvements and bug fixes. Although this is technically a minor release, this new version does come with some minor breaking changes:

• The default value of clean_workdir was changed from True to False.
• The automatic_parallelization feature of the PwBaseWorkChain was removed, as this was badly broken with no clear path to fixing it. Moreover, v7.1 of Quantum ESPRESSO has implemented some basic automated parallelization for pw.x when no parallelization flags are specified.
• Work chains no longer set/override static inputs inside the steps of their outline. All defaults are moved to the protocol files instead, and it is recommended to always use the get_builder_from_protocol() method to run a work chain. For more details, see the corresponding PR.

Support for Quantum ESPRESSO v7.2 pw.x parsing was added, as well as the HubbardStructureData data plugin and corresponding implementation in the PwCalculation plugin to support the new input syntax for using Hubbard corrections in the pw.x code.

For ph.x, the symmetry labels printed in the stdout after the mode frequencies are now parsed for each q-point. In the case of restarts in the PhBaseWorkChain, care has been taken to properly parse these symmetry labels from the separate output files and merge them, so the output_parameters are the same with or without restarts.

The XpsWorkChain has been added to compute the XPS spectra using core-hole pseudo potentials and the pw.x code. The work chain can handle both molecules and crystals. The chemical shifts, as well as the cole-level binding energy can be obtained.

Finally, improved error handling for the PwBaseWorkChain was implemented for several typical failure modes of the pw.x code, and the CRASH file is now also retrieved, as this will be the default location of error messages from Quantum ESPRESSO v7.2 onwards.

‼️ Breaking changes

• Protocols: Set clean_workdir default to False [f8e512f]
• PwBaseWorkChain: Remove automatic_parallelization input [5cae75f]
• Protocols: Move all static work chain inputs to protocol [01f1470]

v3.0.0:

This is the first version to support aiida-core~=1.0 and since the API of aiida-core changed significantly, the code of aiida-quantumespresso did as well. This means that aiida-quantumespresso v2.0 and v3.0 are fundamentally incompatible, which is why we do not include an explicit change log list.

v2.1.0:

Minor release adding a new feature, fixing a critical bug in PwParser and reducing the size of the package

Nota Bene: due to a critical bug discoverd in the PwParser (see below) the parser version has been updated to v2.1.0. Calculations parsed with an older version potentially contain incorrect reduced symmetries in the output_parameters node. Instructions to check the version of the parser that was used, can be found in the documentation

Improvements

• Added support for the ATOMIC_FORCES card in the PwCalculation plugin [#168]
• Tests and fixture data have been removed from the main package, massively reducing distribution size [#154]

Critical bug fixes

• The mapping of the raw symmetry operations onto a reduced set in the PwParser contained a bug and mapped incorrect rotations [#171]

Minor bug fixes

• Fix a bug in ProjwfcParser where due to improper sorting, projections were associated with the wrong output files [#165]
• Adapt the keyword type to node_type in the Node.get_outputs method [#143]
• Fix a missing parameter in the string formatter of one of the error handlers of PwBaseWorkChain [#158]

v2.0.1:

Patch release with some small bug fixes

Update to newer versions of Quantum ESPRESSO

• Add the input helper XML files for v6.0, v6.1 and v6.2 [#135]

Bug fixes

• Parse the standard output in the PwParser even if XML file is missing in order to still get errors in output parameters [#133]
• Bugfix for the _error_handlers list attribute from BaseRestartWorkChain that is now appended to the correct list[#127]
• Number of minor bugfixes to the PwParser to adapt to the updated AiiDA API [#123] [#138]
• Fix a bug causing cmdline args to be ignored in namelists.py [#122]

v2.0.0:

Major release with a lot of new functionality, mostly centered around the workflows

Improvements

• Implemented the BaseRestartWorkChain which defines much of the required scaffolding for any base workchain that launches a calculation [#75]
• Add the Q2rBaseWorkChain and MatdynBaseWorkChain [#93]
• Use the update wrappers for SeeKpath in aiida-core in the PwBandsWorkChain [#104]
