atomate2 is a library of materials science workflows

Documentation | PyPI | GitHub

Atomate2 is a free, open-source software for performing complex materials science workflows using simple Python functions. Features of atomate2 include

• It is built on open-source libraries: pymatgen, custodian, jobflow, and jobflow-remote or FireWorks.
• A library of "standard" workflows to compute a wide variety of desired materials properties.
• The ability scale from a single material, to 100 materials, or 100,000 materials.
• Easy routes to modifying and chaining workflows together.
• It can build large databases of output properties that you can query, analyze, and share in a systematic way.
• It automatically keeps meticulous records of jobs, their directories, runtime parameters, and more.

Workflows

Some of the workflows available in atomate2 are:

• electronic band structures
• elastic, dielectric, and piezoelectric tensors
• one-shot electron-phonon interactions
• electronic transport using AMSET
• phonons using phonopy
• defect formation energy diagrams
• Lobster bonding analysis with lobsterpy

It is easy to customise and compose any of the above workflows.

Quick start

Workflows in atomate2 are written using the jobflow library. Workflows are generated using Maker objects which have a consistent API for modifying input settings and chaining workflows together. Below, we demonstrate how to run a band structure workflow (see the documentation for more details). In total, 4 VASP calculations will be performed:

1. A structural optimisation.
2. A self-consistent static calculation on the relaxed geometry.
3. A non-self-consistent calculation on a uniform k-point mesh (for the density of states).
4. A non-self-consistent calculation on a high symmetry k-point path (for the line mode band structure).

from atomate2.vasp.flows.core import RelaxBandStructureMaker
from jobflow import run_locally
from pymatgen.core import Structure

# construct a rock salt MgO structure
mgo_structure = Structure(
    lattice=[[0, 2.13, 2.13], [2.13, 0, 2.13], [2.13, 2.13, 0]],
    species=["Mg", "O"],
    coords=[[0, 0, 0], [0.5, 0.5, 0.5]],
)

# make a band structure flow to optimise the structure and obtain the band structure
bandstructure_flow = RelaxBandStructureMaker().make(mgo_structure)

# run the flow
run_locally(bandstructure_flow, create_folders=True)

Before the above code can run successfully, you'll need to

• tell pymatgen where to find your pseudopotential files
• tell atomate2 where to find your VASP binary
• (optionally) prepare an external database to store the job output

See the installation steps for details how to set all of this up.

In this example, we execute the workflow immediately. In many cases, you might want to perform calculations on several materials simultaneously. To achieve this, all atomate2 workflows can be run using the jobflow-remote or FireWorks software. See the jobflow-remote-specific documentation or fireworks-specific documentation for more details.

Installation

Atomate2 is a Python 3.10+ library and can be installed using pip. Full installation and configuration instructions are provided in the installation tutorial.

Tutorials

The documentation includes comprehensive tutorials and reference information to get you started:

• Introduction to running workflows
• Using atomate2 with FireWorks
• Overview of key concepts
• List of VASP workflows
• Executable tutorials for different workflows

In March 2025, the first dedicated school on atomate2 (including the workflow language jobflow and the workflow manager jobflow-remote) took place, and one can access the video material here:

• Jobflow and Jobflow-remote
• atomate2
• Advanced Workflows in atomate2: Part 1
• Advanced Workflows in atomate2: Part 2
