Experimental factor#
lamindb provides access to the following public protein ontologies through lnschema-bionty:
Here we show how to access and search experimental factor ontologies to standardize new data.
Setup#
!lamin init --storage ./test-experimental-factor --schema bionty

PublicOntology objects#
Let us create a public ontology accessor with public(), which chooses a default public ontology source from PublicSource. It’s a PublicOntology object, which you can think about as a public registry:
public = lb.ExperimentalFactor.public()
public
💡 loaded instance: testuser1/test-experimental-factor
PublicOntology
Entity: ExperimentalFactor
Organism: all
Source: efo, 3.57.0
#terms: 17352
📖 .df(): ontology reference table
🔎 .lookup(): autocompletion of terms
🎯 .search(): free text search of terms
✅ .validate(): strictly validate values
🧐 .inspect(): full inspection of values
👽 .standardize(): convert to standardized names
🪜 .diff(): difference between two versions
🔗 .to_pronto(): Pronto.Ontology object
As for registries, you can export the ontology as a DataFrame:
df = public.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: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 = public.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 = public.lookup(public.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:
public.search("single-cell rna seq").head(3)
| ontology_id | definition | synonyms | parents | molecule | instrument | measurement | __ratio__ | |
|---|---|---|---|---|---|---|---|---|
| name | ||||||||

By default, search also covers synonyms:
public.search("single-cell RNA-seq").head(1)
| ontology_id | definition | synonyms | parents | molecule | instrument | measurement | __ratio__ | |
|---|---|---|---|---|---|---|---|---|
| name | ||||||||

Search another field (default is .name):
public.search(
"assay which analysis the transcriptome of a biological sample",
field=public.definition,
).head()
| ontology_id | name | synonyms | parents | molecule | instrument | measurement | __ratio__ | |

Standardize Experimental Factor identifiers#
Let us generate a DataFrame that stores a number of pathway identifiers, some of which are corrupted:
df_orig = pd.DataFrame(
index=[
"EFO:0011021",
"EFO:1002050",
"EFO:1002047",
"EFO:1002049",
"This readout does not exist",
]
)
df_orig
| EFO:0011021 |
|---|
| EFO:1002050 |
| EFO:1002047 |
| EFO:1002049 |
| This readout does not exist |
We can check whether any of our values are validated against the ontology reference:
validated = public.validate(df_orig.index, public.ontology_id)
df_orig.index[~validated]
✅ 4 terms (80.00%) are validated
❗ 1 term (20.00%) is not validated: This readout does not exist
Index(['This readout does not exist'], dtype='object')
Ontology source versions#
For any given entity, we can choose from a number of versions:
lb.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 | |

When instantiating a Bionty object, we can choose a source or version:
public_source = lb.PublicSource.filter(
source="efo", version="3.48.0", organism="all"
).one()
public = lb.ExperimentalFactor.public(public_source=public_source)
