slices 2.0.4

SLICES

Simplified Line-Input Crystal-Encoding System

This software implementes Simplified Line-Input Crystal-Encoding System (SLICES), the first invertible and invariant crystal representation.

It has several main functionalities:

• Encode crystal structures into SLICES strings
• Reconstruct original crystal structures from their SLICES strings (Text2Crystal)
• Generate crystals with desired properties using conditional RNN (Inverse Design)

We also provide a codeocean capsule (a modular container for the software environment along with code and data, that runs in a browser), allowing one-click access to guaranteed computational reproducibility of SLICES's benchmark. [Codeocean Capsule]

Installation

# pip config set global.index-url https://pypi.tuna.tsinghua.edu.cn/simple (use this if you are in China)
conda env create --name slices --file=environments.yml
conda activate slices
pip install slices
#If you're in China, use this command instead: "pip install slices -i https://pypi.tuna.tsinghua.edu.cn/simple".

Please note that this installtion method is intended for Linux operating systems like Ubuntu and CentOS. Unfortunately, SLICES is not directly compatible with Windows or MacOS due to the modified XTB binary was compiled on Linux. To run SLICES on Windows or MacOS, one can run SLICES with docker, referring to Jupyter backend setup.

If "TypeError: bases must be types" occurs when you use SLICES library, then do this:

pip install protobuf==3.20.0

If errors still occur, then you can run SLICES with docker, referring to Jupyter backend setup.

Examples

Crystal to SLICES and SLICES to crystal

Converting a crystal structure to its SLICES string and converting this SLICES string back to its original crystal structure. Suppose we wish to convert the crystal structure of NdSiRu (mp-5239,https://next-gen.materialsproject.org/materials/mp-5239?material_ids=mp-5239) to its SLICES string and converting this SLICES string back to its original crystal structure. The python code below accomplishes this:

from slices.core import SLICES
from pymatgen.core.structure import Structure
# obtaining the pymatgen Structure instance of NdSiRu
original_structure = Structure.from_file(filename='NdSiRu.cif')
# creating an instance of the InvCryRep Class (initialization)
backend=SLICES()
# converting a crystal structure to its SLICES string
slices_NdSiRu=backend.structure2SLICES(original_structure) 
# converting a SLICES string back to its original crystal structure and obtaining its M3GNet_IAP-predicted energy_per_atom
reconstructed_structure,final_energy_per_atom_IAP = backend.SLICES2structure(slices_NdSiRu)
print('SLICES string of NdSiRu is: ',slices_NdSiRu)
print('\nReconstructed_structure is: ',reconstructed_structure)
print('\nfinal_energy_per_atom_IAP is: ',final_energy_per_atom_IAP,' eV/atom')
# if final_energy_per_atom_IAP is 0, it means the M3GNet_IAP refinement failed, and the reconstructed_structure is the ZL*-optimized structure.

Augment SLICES and canonicalize SLICES

Converting a crystal structure to its SLICES string and perform data augmentation (50x), then reduce these 50 SLICES to 1 canonical SLICES with get_canonical_SLICES.

from slices.core import SLICES
from pymatgen.core.structure import Structure
from pymatgen.analysis.structure_matcher import StructureMatcher, ElementComparator
# obtaining the pymatgen Structure instance of Sr3Ru2O7
original_structure = Structure.from_file(filename='Sr3Ru2O7.cif')
# creating an instance of the InvCryRep Class (initialization)
backend=SLICES(graph_method='crystalnn')
# converting a crystal structure to its SLICES string and perform data augmentation (50x)
slices_list=backend.structure2SLICESAug_atom_order(structure=original_structure,num=50) 
slices_list_unique=list(set(slices_list))
cannon_slices_list=[]
for i in slices_list_unique:
    cannon_slices_list.append(backend.get_canonical_SLICES(i))
# test get_canonical_SLICES
print(len(slices_list),len(set(cannon_slices_list)))
# 50 SLICES generated by data augmentation has been reduced to 1 canonical SLICES

Jupyter backend setup

(1) Download this repo and unzipped it.

(2) Put Materials Project's new API key in "APIKEY.ini".

(3) Edit "CPUs" in "slurm.conf" to set up the number of CPU threads available for the docker container.

(4) Run following commands in terminal (Linux or WSL2 Ubuntu on Win11)

# Download SLICES_docker with pre-installed SLICES and other relevant packages. 
docker pull xiaohang07/slices:v9  
# You can download the compressed docker image v9 at https://figshare.com/s/260701a1accd0192de20 if docker pull does not work. 
# Then you can load this docker image using the following command: 
xz -dc slices_v9.tar.xz | docker load
# Make entrypoint_set_cpus.sh executable 
sudo chmod +x entrypoint_set_cpus_jupyter.sh
# Repalce "[]" with the absolute path of this repo's unzipped folder to setup share folder for the docker container.
