Change Log

v3.3.6

  • Add py.typed to properly detect type hints by @Andrew-S-Rosen
  • snb-run updates to improve efficiency

v3.3.5

  • Enforce doped>=2.4.4 requirement.

v3.3.4

  • Make oxidation state guessing more efficient.
  • Update Quantum Espresso and FHI-aims IO functions to work with new (and old) ASE release.
  • Minor updates to ensure compatibility with recent pymatgen release.
  • Allow unrecognised defect names when plotting.

v3.3.3

  • Add verbose option to more parsing/plotting functions for better control of output detail.
  • Improve effiency & robustness of oxidation state handling.
  • Miscellaneous efficiency (e.g. memory reduction) and robustness updates.
  • Improved GitHub Actions test efficiency.

v3.3.2

  • Add verbose options to io.parse_energies() and snb-parse, also used in snb-plot and snb-analyse, and set to False by default to reduce verbosity of certain SnB CLI commands.
  • Use doped functions to make oxi-state guessing (and thus defect initialisation) more efficient.
  • Miscellaneous efficiency and robustness updates.
  • Testing updates.

v3.3.1

  • distortion_metadata.json for each defect now saved to the individual defect folders (as well as the combined total distortion metadata in the top level folder) – more likely to be retained by the user when ``scp``ing around etc.
  • Minor updates:
    • Refactor _format_defect_name to format_defect_name from doped (now a public function)
    • Update snb-run to avoid possible 'file exists' warning
    • Update tutorials/notebooks to specify vasp_nkred_std to streamline workflow
    • Remove unnecessary tutorials folder with duplicate tutorial notebook (to reduce workload).
    • Add Binder/Colab buttons to run tutorials in the cloud from docs
    • Default verbosity updates (quieten some unnecessary info messages)
    • Make distortion_metadata overwriting/combining more robust and less (unnecessarily) verbose
  • Bugfix of snb-run from v3.3.0: If max number of electronic steps (NELM) threshold was reached in an ionic step, it would be falsely recognised as converged (due to unconverged being in the OUTCAR). This would only affect snb-run behaviour in some cases with v3.3.0, and if so the user should be warned anyway with Bond_Distortion_X not fully relaxed when later running snb-parse/snb-plot/snb-groundstate. Now fixed. To double check, one can update ShakeNBreak and just re-run snb-run, and any affected distortions will be correctly determined as unconverged and be re-submitted.

v3.3.0

  • Add Dimer distortion as a targeted distortion for dimer reconstructions. It pushes two of the defect NN to a distance of 2 A.
  • Add option distorted_atoms to the Distortion class to allow users to specify the indexes of the atoms to distort.
  • Update tests to check the new functionality.
  • Update get_homoionic_bonds to detect homoionic bonds between different cations/anions (rather than just bonds between the same element)
  • Fix issue with snb-generate when no defect name was specified (by adding unrelaxed=True when calling get_defect_name_from_entry)
  • Update functions that read OUTCARs to be able to read OUTCAR.gz files too
  • Update energies parsing to still work when all distortions are high energy, but warn the user about this (i.e. only Unperturbed)
  • Update snb-run to add early-on detection of distortions that are stuck in high energy basins and rename them to "High_Energy" to avoid continuing their relaxation
  • Miscellaneous efficiency improvements and bug fixes

v3.2.3

  • Ensure the sorted pymatgen Structure is created for the VASP input (fixes a rare bug in v3.2.1 and v3.2.2 where for certain structures the order of elements in the POSCAR was not properly sorted, which is usually fine, but messed with the ROPT INCAR setting).
  • Plotting format updates (make legend frame more transparent to make datapoints behind it easier to see).
  • Update tests
  • Update docs (note about handling AFM systems)

v3.2.2

  • Consolidate SnB/doped INCAR defaults and remove redundant settings.
  • Ensure backwards compatiblity in defect folder name handling.
  • Fix bug in get_site_magnetizations.

v3.2.1

  • Update CLI config handling.
  • Remove shakenbreak.vasp module and use doped VASP file writing functions directly.
  • Add INCAR/KPOINTS/POTCAR file writing tests. test_local.py now deleted as these tests are now automatically run in test_input.py/test_cli.py if `POTCAR`s available.

v3.2.0

  • Following the major release of doped v2.0, now compatible with the new pymatgen defects code (pymatgen>2022.7.25), this update:

    • Allows input of doped DefectsGenerator object to Distortions
    • Updates the tutorials to reflect the current recommended workflow of generating defects with doped and then applying ShakeNBreak, no longer requiring separate virtual environments 🎉

v3.1.0

  • Update dependencies, as hiphive=1.2 has been released, making ShakeNBreak compatible with `python=3.11`🎉

v3.0.0

  • Switch to semantic versioning
  • Update rattling functions to handle primitive bulk materials as well as supercells.
  • Add check to snb-run if there are multiple `OUTCAR`s present with one or less ionic steps, and if this is also the case for the current run -> warn the user.
  • Small fixes, formatting and docs updates.

v23.06.23

  • Add snb-mag function, and automatically check the magnetisation from ISPIN = 2 OUTCAR files when continuing relaxations with snb-run (and change to ISPIN = 1 if magnetisation is negligible).
  • Update handling of minimum distances and oxidation states, to deal with single-atom primitive unit cells and systems where pymatgen cannot guess the oxidation state (e.g. single-elements, intermetallics etc).
  • Docs updates

v23.06.03

  • Make parsing of `DefectEntry`s more robust.
  • Update dependencies (now supporting python=3.10 due to numba updates)
  • Refactor CITATION.cff to CITATIONS.md
  • Update docs, formatting and cleanup.

v23.04.27

  • Update numpy requirement to numpy>=1.21.2 to fix numpy.typing.NDArray import error.
  • Add News & Views free-to-read link to docs

v23.04.26

  • Updates to snb-run (copy job from parent directory if present, switch to ALGO = All if poor electronic convergence...)
  • Make format_defect_name() more robust
  • Update docs and README.md with published article links
  • Formatting and cleanup
  • Make oxidation state guessing more efficient (previously was causing bottleneck with large cells)
  • Fix oxidation state guessing for rare elements
  • Add note to Tips docs page about bulk phase transformation behaviour
  • Refactor to json rather than pickle

v23.02.08

  • Change numpy version requirement in docs/requirements.txt to numpy>=1.21 to work with numpy.typing.NDArray.

v23.02.02

  • Refactor Distortions() class to take in DefectEntry objects as input, rather than Defect objects, to be
