CellTypeΒΆ

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

  1. Cell Ontology

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

import bionty as bt
import pandas as pd
πŸ’‘ connected lamindb: testuser1/test-public-ontologies

PublicOntology objectsΒΆ

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:

celltypes = bt.CellType.public(organism="all")
celltypes
PublicOntology
Entity: CellType
Organism: all
Source: cl, 2023-08-24
#terms: 2894

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 = celltypes.df()
df.head()

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

Look up termsΒΆ

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

lookup = celltypes.lookup()

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

lookup.cd8_positive_alpha_beta_t_cell
CellType(ontology_id='CL:0000625', name='CD8-positive, alpha-beta T cell', definition='A T Cell Expressing An Alpha-Beta T Cell Receptor And The Cd8 Coreceptor.', synonyms='CD8-positive, alpha-beta T-cell|CD8-positive, alpha-beta T lymphocyte|CD8-positive, alpha-beta T-lymphocyte', parents=array(['CL:0000791'], dtype=object))

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

lookup_dict = lookup.dict()
lookup_dict["CD8-positive, alpha-beta T cell"]
CellType(ontology_id='CL:0000625', name='CD8-positive, alpha-beta T cell', definition='A T Cell Expressing An Alpha-Beta T Cell Receptor And The Cd8 Coreceptor.', synonyms='CD8-positive, alpha-beta T-cell|CD8-positive, alpha-beta T lymphocyte|CD8-positive, alpha-beta T-lymphocyte', parents=array(['CL:0000791'], dtype=object))

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

lookup = celltypes.lookup(celltypes.ontology_id)
lookup.cl_0000625
CellType(ontology_id='CL:0000625', name='CD8-positive, alpha-beta T cell', definition='A T Cell Expressing An Alpha-Beta T Cell Receptor And The Cd8 Coreceptor.', synonyms='CD8-positive, alpha-beta T-cell|CD8-positive, alpha-beta T lymphocyte|CD8-positive, alpha-beta T-lymphocyte', parents=array(['CL:0000791'], dtype=object))

Search termsΒΆ

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

celltypes.search("CD8 positive T cell").head(3)
ontology_id definition synonyms parents __ratio__
name
Tc1 cell CL:0000917 A Cd8-Positive, Alpha-Beta Positive T Cell Tha... Tc1 T lymphocyte|Tc1 T-cell|Tc1 T cell|T-cytot... [CL:0000908] 95.000000

By default, search also covers synonyms:

celltypes.search("Tc1 T lymphocyte").head(3)
ontology_id definition synonyms parents __ratio__
name

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

celltypes.search("Tc1 T lymphocyte", synonyms_field=None).head(3)
ontology_id definition synonyms parents __ratio__
name

Peyer's patch lymphocyte CL:0009014 A Lymphocyte That Is Part Of A Peyer'S Patch. ... Peyer's patch resident lymphocyte [CL:0000542] 65.000000

Search another field (default is .name):

celltypes.search(
    "CD8 positive alpha beta T cell",
    field=celltypes.definition,
).head()
ontology_id name synonyms parents __ratio__

Standardize CellType identifiersΒΆ

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

df_orig = pd.DataFrame(
    index=[
        "Boettcher cell",
        "bone marrow cell",
        "interstitial cell of ovary",
        "pancreatic ductal cell",
        "This celltype does not exist",
    ]
)
df_orig
Boettcher cell
bone marrow cell
interstitial cell of ovary
pancreatic ductal cell
This celltype does not exist

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

validated = celltypes.validate(df_orig.index, celltypes.name)
df_orig.index[~validated]
βœ… 4 terms (80.00%) are validated
❗ 1 term (20.00%) is not validated: This celltype does not exist
Index(['This celltype does not exist'], dtype='object')

Ontology source versionsΒΆ

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

bt.PublicSource.filter(entity="CellType").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 = bt.PublicSource.filter(
    source="cl", version="2023-04-20", organism="all"
).one()
celltypes= bt.CellType.public(public_source=public_source)
