ExperimentalFactor

lamindb provides access to the following public ExperimentalFactor ontologies through bionty:

  1. Experimental Factor Ontology

Here we show how to access and search ExperimentalFactor ontologies to standardize new data.

import bionty as bt
import pandas as pd

PublicOntology objects

Let us create a public ontology accessor with .public method, which chooses a default public ontology source from Source. It’s a PublicOntology object, which you can think about as a public registry:

experimentalfactors = bt.ExperimentalFactor.public(organism="all")
experimentalfactors
 connected lamindb: testuser1/test-public-ontologies
PublicOntology
Entity: ExperimentalFactor
Organism: all
Source: efo, 3.70.0
#terms: 18131

As for registries, you can export the ontology as a DataFrame:

df = experimentalfactors.df()
df.head()
name definition synonyms parents molecule instrument measurement
ontology_id
EFO:0000001 experimental factor An Experimental Factor In Array Express Which ... ExperimentalFactor [] None None None
EFO:0000002 CS57511 Cs57511 Is An Arabidopsis Thaliana Strain As D... None [] None None None
EFO:0000003 CS57512 Cs57512 Is An Arabidopsis Thaliana Strain As D... None [] None None None
EFO:0000004 CS57515 Cs57515 Is An Arabidopsis Thaliana Strain As D... None [] None None None
EFO:0000005 CS57520 Cs57520 Is An Arabidopsis Thaliana Strain As D... None [] None None None

Unlike registries, you can also export it as a Pronto object via public.ontology.

Look up terms

As for registries, terms can be looked up with auto-complete:

lookup = experimentalfactors.lookup()

The . accessor provides normalized terms (lower case, only contains alphanumeric characters and underscores):

lookup.sequencer
ExperimentalFactor(ontology_id='EFO:0003739', name='sequencer', definition=None, synonyms=None, parents=array(['EFO:0000548'], dtype=object), molecule=None, instrument=None, measurement=None)

To look up the exact original strings, convert the lookup object to dict and use the [] accessor:

lookup_dict = lookup.dict()
lookup_dict["sequencer"]
ExperimentalFactor(ontology_id='EFO:0003739', name='sequencer', definition=None, synonyms=None, parents=array(['EFO:0000548'], dtype=object), molecule=None, instrument=None, measurement=None)

By default, the name field is used to generate lookup keys. You can specify another field to look up:

lookup = experimentalfactors.lookup(experimentalfactors.ontology_id)
lookup.efo_0003739
ExperimentalFactor(ontology_id='EFO:0003739', name='sequencer', definition=None, synonyms=None, parents=array(['EFO:0000548'], dtype=object), molecule=None, instrument=None, measurement=None)

Search terms

Search behaves in the same way as it does for registries:

experimentalfactors.search("single-cell rna seq").head(3)
name definition synonyms parents molecule instrument measurement
ontology_id
EFO:0008913 single-cell RNA sequencing A Protocol That Provides The Expression Profil... single-cell RNA-seq|scRNA-seq|single cell RNA ... [EFO:0001457, EFO:0007832] RNA assay single cell sequencing None

EFO:0022488 Smart-seq3 Smart-Seq3 Is An Advanced Single-Cell Rna Sequ... None [EFO:0010184] None None None

By default, search also covers synonyms and all other fileds containing strings:

experimentalfactors.search("single-cell RNA-seq").head(3)
name definition synonyms parents molecule instrument measurement
ontology_id
EFO:0008913 single-cell RNA sequencing A Protocol That Provides The Expression Profil... single-cell RNA-seq|scRNA-seq|single cell RNA ... [EFO:0001457, EFO:0007832] RNA assay single cell sequencing None

Search specific field (by default, search is done on all fields containing strings):

experimentalfactors.search(
    "protocol that provides the expression profiles of single cells",
    field=experimentalfactors.definition,
).head()
name definition synonyms parents molecule instrument measurement
ontology_id
EFO:0008913 single-cell RNA sequencing A Protocol That Provides The Expression Profil... single-cell RNA-seq|scRNA-seq|single cell RNA ... [EFO:0001457, EFO:0007832] RNA assay single cell sequencing None

Standardize ExperimentalFactor identifiers

Let us generate a DataFrame that stores a number of ExperimentalFactor identifiers, some of which corrupted:

df_orig = pd.DataFrame(
    index=[
        "EFO:0011021",
        "EFO:1002050",
        "EFO:1002047",
        "EFO:1002049",
        "This experimentalfactor does not exist",
    ]
)
df_orig
EFO:0011021
EFO:1002050
EFO:1002047
EFO:1002049
This experimentalfactor does not exist

We can check whether any of our values are validated against the ontology reference:

validated = experimentalfactors.validate(df_orig.index, experimentalfactors.name)
df_orig.index[~validated]
! 5 unique terms (100.00%) are not validated: 'EFO:0011021', 'EFO:1002050', 'EFO:1002047', 'EFO:1002049', 'This experimentalfactor does not exist'
Index(['EFO:0011021', 'EFO:1002050', 'EFO:1002047', 'EFO:1002049',
       'This experimentalfactor does not exist'],
      dtype='object')

Ontology source versions

For any given entity, we can choose from a number of versions:
