ExperimentalFactor#

lamindb provides access to the following public protein 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 PublicSource. It’s a PublicOntology object, which you can think about as a public registry:

experimentalfactors = bt.ExperimentalFactor.public(organism="all")
experimentalfactors
PublicOntology
Entity: ExperimentalFactor
Organism: all
Source: efo, 3.57.0
#terms: 17352

πŸ“– .df(): ontology reference table
πŸ”Ž .lookup(): autocompletion of terms
🎯 .search(): free text search of terms
βœ… .validate(): strictly validate values
🧐 .inspect(): full inspection of values
πŸ‘½ .standardize(): convert to standardized names
πŸͺœ .diff(): difference between two versions
πŸ”— .to_pronto(): Pronto.Ontology object

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)
ontology_id definition synonyms parents molecule instrument measurement __ratio__
name

By default, search also covers synonyms:

experimentalfactors.search("single-cell RNA-seq").head(3)
ontology_id definition synonyms parents molecule instrument measurement __ratio__
name
single-cell RNA sequencing EFO:0008913 A Protocol That Provides The Expression Profil... scRNA-seq|single cell RNA sequencing|single-ce... [EFO:0001457, EFO:0007832] RNA assay single cell sequencing None 100.000000

You can turn this off synonym by passing synonyms_field=None:

experimentalfactors.search("single-cell RNA-seq", synonyms_field=None).head(3)
ontology_id definition synonyms parents molecule instrument measurement __ratio__
name
single-cell RNA sequencing EFO:0008913 A Protocol That Provides The Expression Profil... scRNA-seq|single cell RNA sequencing|single-ce... [EFO:0001457, EFO:0007832] RNA assay single cell sequencing None 84.444444

Search another field (default is .name):

experimentalfactors.search(
    "assay which analysis the transcriptome of a biological sample",
    field=experimentalfactors.definition,
).head()
ontology_id name synonyms parents molecule instrument measurement __ratio__

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:0011021EFO:1002050EFO:1002047EFO:1002049This 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]
❗ 1 term (100.00%) is not validated: EFO:0011021EFO:1002050EFO:1002047EFO:1002049This experimentalfactor does not exist
Index(['EFO:0011021EFO:1002050EFO:1002047EFO:1002049This experimentalfactor does not exist'], dtype='object')

Ontology source versions#

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

bt.PublicSource.filter(entity="ExperimentalFactor").df()
uid entity organism currently_used source source_name version url md5 source_website created_at updated_at created_by_id
