# `ShakeNBreak` (`SnB`)
<a href="https://shakenbreak.readthedocs.io/en/latest/"><img align="right" width="400" src="https://raw.githubusercontent.com/SMTG-Bham/ShakeNBreak/main/docs/toc.png"></a> `ShakeNBreak` is a defect structure-searching method employing chemically-guided bond distortions to
locate ground-state and metastable structures of point defects in solid materials. [Docs here!](https://shakenbreak.readthedocs.io/en/latest/)
Main features include:
1. Defect structure generation:
* Automatic generation of distorted structures for input defects
* Optionally, input file generation for geometry optimisation with several codes (`VASP`, `CP2K`, `Quantum-Espresso`, `CASTEP` & `FHI-aims`)
2. Analysis:
* Parsing of geometry relaxation results
* Plotting of final energies versus distortion to demonstrate what energy-lowering reconstructions have been identified
* Coordination & bonding analysis to investigate the physico-chemical factors driving an energy-lowering distortion
* Magnetisation analysis (currently only supported for `VASP`)
The code currently supports `VASP`, `CP2K`, `Quantum-Espresso`, `CASTEP` & `FHI-aims`. Code contributions to support additional solid-state packages are welcome.

## Installation
`ShakeNBreak` can be installed using `pip`:
```bash
pip install shakenbreak
```
Alternatively if needed, it can also be installed from `conda` with:
```bash
conda install -c conda-forge shakenbreak
```
If using `VASP`, in order for `ShakeNBreak` to automatically generate the pseudopotential input files (`POTCAR`s), your local `VASP` pseudopotential directory must be set in the `pymatgen` configuration file `$HOME/.pmgrc.yaml` as follows:
```bash
PMG_VASP_PSP_DIR: <Path to VASP pseudopotential top directory>
```
Within your `VASP` pseudopotential top directory, you should have a folder named `POT_GGA_PAW_PBE`
which contains the `POTCAR.X(.gz)` files (in this case for PBE `POTCAR`s). Please refer to the [`doped` Installation docs](https://doped.readthedocs.io/en/latest/Installation.html) if you have
difficulty with this.
The font Montserrat ([Open Font License](https://scripts.sil.org/cms/scripts/page.php?site_id=nrsi&id=OFL)) will be installed with the package, and will be used by default for plotting.
### Developer installation
For development work, ShakeNBreak can also be installed from a copy of the source directory:
1. Download `ShakeNBreak` source code using the command:
```bash
git clone https://github.com/SMTG-Bham/ShakeNBreak
```
2. Navigate to root directory:
```bash
cd ShakeNBreak
```
3. Install the code, using the command:
```bash
pip install -e .
```
This command tries to obtain the required packages and their dependencies and install them automatically.
## Usage
### Python API
`ShakeNBreak` can be used through a Python API, as exemplified in the [SnB Python API tutorial](https://shakenbreak.readthedocs.io/en/latest/ShakeNBreak_Example_Workflow.html), with more info available on the [docs](https://readthedocs.org/projects/shakenbreak).
### Command line interface
Alternatively, the code can be used via the command line:
The functions provided include:
* [`snb-generate`](https://shakenbreak.readthedocs.io/en/latest/shakenbreak.cli.html#snb-generate): Generate distorted structures for a given defect
* [`snb-generate_all`](https://shakenbreak.readthedocs.io/en/latest/shakenbreak.cli.html#snb-generate-all): Generate distorted structures for all defects present in the specified/current directory
* [`snb-run`](https://shakenbreak.readthedocs.io/en/latest/shakenbreak.cli.html#snb-run): Submit geometry relaxations to the HPC scheduler
* [`snb-parse`](https://shakenbreak.readthedocs.io/en/latest/shakenbreak.cli.html#snb-parse): Parse the results of the geometry relaxations and write them to a `yaml` file
* [`snb-analyse`](https://shakenbreak.readthedocs.io/en/latest/shakenbreak.cli.html#snb-analyse): Generate `csv` files with energies and structural differences between the final configurations
* [`snb-plot`](https://shakenbreak.readthedocs.io/en/latest/shakenbreak.cli.html#snb-plot): Generate plots of energy vs distortion, with the option to include a colorbar to quantify structural differences
* [`snb-regenerate`](https://shakenbreak.readthedocs.io/en/latest/shakenbreak.cli.html#snb-regenerate): Identify defect species undergoing energy-lowering distortions and test these distortions for the other charge states of the defect
* [`snb-groundstate`](https://shakenbreak.readthedocs.io/en/latest/shakenbreak.cli.html#snb-groundstate): Save the ground state structures to a ``Groundstate`` directory for continuation runs
More information about each function and its inputs/outputs are available from the [CLI section of the docs](https://shakenbreak.readthedocs.io/en/latest/shakenbreak.cli.html#commands) or using `-h` help option (e.g. `snb -h`).
We recommend at least looking through the [tutorials](https://shakenbreak.readthedocs.io/en/latest/Tutorials.html) when first starting to use `ShakeNBreak`, to familiarise yourself with the full functionality and workflow.
## Code Compatibility
`ShakeNBreak` is built to natively function using `pymatgen` `Defect` objects ([docs available here](https://materialsproject.github.io/pymatgen-analysis-defects/)) and be compatible with the most recent version of `pymatgen`.
If you are receiving `pymatgen`-related errors when using `ShakeNBreak`, you may need to update `pymatgen` and/or `ShakeNBreak`, which can be done with:
```bash
pip install --upgrade pymatgen shakenbreak
```
`ShakeNBreak` can take `pymatgen` `Defect` objects as input (to then generate the trial distorted structures),
**_but also_** can take in `pymatgen` `Structure` objects, `doped` defects or structure files
(e.g. `POSCAR`s for `VASP`) as inputs. As such, it should be compatible with any defect code
(such as [`doped`](https://doped.readthedocs.io/en/latest/index.html), [`pydefect`](https://github.com/kumagai-group/pydefect),
[`PyCDT`](https://github.com/mbkumar/pycdt), [`PyLada`](https://github.com/pylada/pylada-defects),
[`DASP`](http://hzwtech.com/files/software/DASP/htmlEnglish/index.html), [`Spinney`](https://gitlab.com/Marrigoni/spinney/-/tree/master),
[`DefAP`](https://github.com/DefAP/defap), [`PyDEF`](https://github.com/PyDEF2/PyDEF-2.0)...) that generates these files.
Please let us know if you have any issues with compatibility, or if you would like to see any additional features added to `ShakeNBreak` to make it more compatible with your code.
