pymatgen.ext.matproj module

This module provides classes to interface with the Materials Project REST API v2 to enable the creation of data structures and pymatgen objects using Materials Project data.

To make use of the Materials API, you need to be a registered user of the Materials Project, and obtain an API key by going to your dashboard at https://www.materialsproject.org/dashboard.

exception MPRestError[source]

Bases: Exception

Exception class for MPRestAdaptor. Raised when the query has problems, e.g., bad query format.

class MPRester(api_key=None, endpoint=None, include_user_agent=True)[source]

Bases: object

A class to conveniently interface with the Materials Project REST interface. The recommended way to use MPRester is with the “with” context manager to ensure that sessions are properly closed after usage:

with MPRester("API_KEY") as m:
    do_something

MPRester uses the “requests” package, which provides for HTTP connection pooling. All connections are made via https for security.

For more advanced uses of the Materials API, please consult the API documentation at https://github.com/materialsproject/mapidoc.

Parameters

  • api_key (str) – A String API key for accessing the MaterialsProject REST interface. Please obtain your API key at https://www.materialsproject.org/dashboard. If this is None, the code will check if there is a “PMG_MAPI_KEY” setting. If so, it will use that environment variable. This makes easier for heavy users to simply add this environment variable to their setups and MPRester can then be called without any arguments.

  • endpoint (str) – Url of endpoint to access the MaterialsProject REST interface. Defaults to the standard Materials Project REST address at “https://materialsproject.org/rest/v2”, but can be changed to other urls implementing a similar interface.

  • include_user_agent (bool) – If True, will include a user agent with the HTTP request including information on pymatgen and system version making the API request. This helps MP support pymatgen users, and is similar to what most web browsers send with each page request. Set to False to disable the user agent.

delete_snl(snl_ids)[source]

Delete earlier submitted SNLs.

Note

As of now, this MP REST feature is open only to a select group of users. Opening up submissions to all users is being planned for the future.

static parse_criteria(criteria_string)[source]

Parses a powerful and simple string criteria and generates a proper mongo syntax criteria.

Parameters

criteria_string (str) –

A string representing a search criteria. Also supports wild cards. E.g., something like “*2O” gets converted to {‘pretty_formula’: {‘$in’: [u’B2O’, u’Xe2O’, u”Li2O”, …]}}

Other syntax examples:

mp-1234: Interpreted as a Materials ID. Fe2O3 or *2O3: Interpreted as reduced formulas. Li-Fe-O or *-Fe-O: Interpreted as chemical systems.

You can mix and match with spaces, which are interpreted as “OR”. E.g., “mp-1234 FeO” means query for all compounds with reduced formula FeO or with materials_id mp-1234.

Returns

A mongo query dict.

query(criteria, properties, chunk_size=500, max_tries_per_chunk=5, mp_decode=True)[source]

Performs an advanced query using MongoDB-like syntax for directly querying the Materials Project database. This allows one to perform queries which are otherwise too cumbersome to perform using the standard convenience methods.

Please consult the Materials API documentation at https://github.com/materialsproject/mapidoc, which provides a comprehensive explanation of the document schema used in the Materials Project (supported criteria and properties) and guidance on how best to query for the relevant information you need.

For queries that request data on more than CHUNK_SIZE materials at once, this method will chunk a query by first retrieving a list of material IDs that satisfy CRITERIA, and then merging the criteria with a restriction to one chunk of materials at a time of size CHUNK_SIZE. You can opt out of this behavior by setting CHUNK_SIZE=0. To guard against intermittent server errors in the case of many chunks per query, possibly-transient server errors will result in re-trying a give chunk up to MAX_TRIES_PER_CHUNK times.

Parameters

  • criteria (str/dict) –

    Criteria of the query as a string or mongo-style dict.

    If string, it supports a powerful but simple string criteria. E.g., “Fe2O3” means search for materials with reduced_formula Fe2O3. Wild cards are also supported. E.g., “\*2O” means get all materials whose formula can be formed as \*2O, e.g., Li2O, K2O, etc.

    Other syntax examples: mp-1234: Interpreted as a Materials ID. Fe2O3 or *2O3: Interpreted as reduced formulas. Li-Fe-O or *-Fe-O: Interpreted as chemical systems.

    You can mix and match with spaces, which are interpreted as “OR”. E.g. “mp-1234 FeO” means query for all compounds with reduced formula FeO or with materials_id mp-1234.

    Using a full dict syntax, even more powerful queries can be constructed. For example, {“elements”:{“$in”:[“Li”, “Na”, “K”], “$all”: [“O”]}, “nelements”:2} selects all Li, Na and K oxides. {“band_gap”: {“$gt”: 1}} selects all materials with band gaps greater than 1 eV.

  • properties (list) – Properties to request for as a list. For example, [“formula”, “formation_energy_per_atom”] returns the formula and formation energy per atom.

  • chunk_size (int) – Number of materials for which to fetch data at a time. More data-intensive properties may require smaller chunk sizes. Use chunk_size=0 to force no chunking – this is useful when fetching only properties such as ‘material_id’.

  • max_tries_per_chunk (int) – How many times to re-try fetching a given chunk when the server gives a 5xx error (e.g. a timeout error).

  • mp_decode (bool) – Whether to do a decoding to a Pymatgen object where possible. In some cases, it might be useful to just get the raw python dict, i.e., set to False.

Returns

List of results. E.g., [{u’formula’: {u’O’: 1, u’Li’: 2.0}}, {u’formula’: {u’Na’: 2.0, u’O’: 2.0}}, {u’formula’: {u’K’: 1, u’O’: 3.0}}, …]
