Manage biological registries¶

This guide shows how to manage metadata for basic biological entities based on plugin bionty.

# !pip install 'lamindb[bionty]'
!lamin init --storage ./test-registries --schema bionty

import lamindb as ln
import bionty as bt

→ connected lamindb: testuser1/test-registries

Seed registries with public ontologies¶

Let’s first populate our CellType registry with the configured public ontology (Cell Ontology):

# check configured public ontology
bt.Source.filter(entity="bionty.CellType", currently_used=True).one()

Source(uid='1Lhf', entity='bionty.CellType', organism='all', name='cl', version='2024-05-15 00:00:00 ', in_db=False, currently_used=True, description='Cell Ontology', url='http://purl.obolibrary.org/obo/cl/releases/2024-05-15/cl.owl', md5='8a8638a9e79567935793e5007704c650', source_website='https://obophenotype.github.io/cell-ontology', created_by_id=1, created_at=2024-10-29 21:22:29 UTC)

# populate the database with the public ontology
bt.CellType.import_from_source()

This is now your in-house CellType registry:

# all public cell types are now available in LaminDB
bt.CellType.df()

You can construct custom hierarchies of records:

# register a new cell type
my_celltype = bt.CellType(name="my new T-cell subtype").save()
# specify "gamma-delta T cell" as a parent
my_celltype.parents.add(gdt_cell)

# visualize hierarchy
gdt_cell.view_parents(distance=2, with_children=True)

Create records from values¶

When accessing datasets, one often encounters bulk references to entities that might be corrupted or standardized using different standardization schemes.

Let’s consider an example based on an AnnData object, in the cell_type annotations of this AnnData object, we find 4 references to cell types:

adata = ln.core.datasets.anndata_with_obs()
adata.obs.cell_type.value_counts()

We’d like to load the corresponding records in our in-house registry to annotate a dataset.

To this end, you’ll typically use from_values, which will both validate & retrieve records that match the values.

cell_types = bt.CellType.from_values(adata.obs.cell_type)
cell_types

Logging informed us that 3 cell types were validated. Since we loaded these records at the same time, we could readily use them to annotate a dataset.

Alternatively, we can retrieve records based on ontology ids:

adata.obs.cell_type_id.unique().tolist()

bt.CellType.from_values(adata.obs.cell_type_id, field=bt.CellType.ontology_id)

Validate & standardize¶

Simple validation of an iterable of values works like so:

bt.CellType.validate(["fat cell", "blood forming stem cell"])

Because these values don’t comply with the registry, they’re not validated!

You can easily convert these values to validated standardized names based on synonyms like so:

bt.CellType.standardize(["fat cell", "blood forming stem cell"])

Alternatively, you can use .from_values(), which will only ever return validated records and automatically standardize under-the-hood:

bt.CellType.from_values(["fat cell", "blood forming stem cell"])

If you are now sure what to do, use .inspect() to get instructions:

bt.CellType.inspect(["fat cell", "blood forming stem cell"]);

We can also add new synonyms to a record like so:

hsc_record.add_synonym("HSC")

And when we encounter this synonym as a value, it will now be standardized using synonyms-lookup, and mapped on the correct registry record:

bt.CellType.standardize(["HSC"])

A special synonym is .abbr (short for abbreviation), which has its own field and can be assigned via:

hsc_record.set_abbr("HSC")

You can create a lookup object from the .abbr field:

cell_types = bt.CellType.lookup("abbr")
hsc = cell_types.hsc
hsc

The same workflow works for all of bionty’s registries.

Manage registries across organisms¶

Several registries are organism-aware (has a .organism field), for instance, Gene.

In this case, API calls that interact with multi-organism registries require an organism argument when there’s ambiguity.

For instance, when validating gene symbols:

bt.Gene.validate(["TCF7", "ABC1"], organism="human")

In contrary, working with Ensembl Gene IDs doesn’t require passing organism, as there’s no ambiguity:

bt.Gene.validate(["ENSG00000000419", "ENSMUSG00002076988"], field=bt.Gene.ensembl_gene_id)

array([ True,  True])

When working with the same organism throughout your analysis/workflow, you can omit the organism argument by configuring it globally:

bt.settings.organism = "mouse"
bt.Gene.from_source(symbol="Ap5b1")

Gene(uid='3b8mHb0MRal4', symbol='Ap5b1', ensembl_gene_id='ENSMUSG00000049562', ncbi_gene_ids='381201', biotype='protein_coding', synonyms='Gm962', description='adaptor-related protein complex 5, beta 1 subunit ', created_by_id=1, source_id=15, organism_id=2, created_at=2024-10-29 21:23:24 UTC)

Track underlying ontology source versions¶

Under-the-hood, source ontology versions are automatically tracked for each registry:

bt.Source.filter(currently_used=True).df()

Create records from specific source¶

By default, new records are imported or created from the "currently_used" public sources which are configured during the instance initialization, e.g.:

Sometimes, the default source doesn’t contain the ontology term you are looking for.

You can then specify to create a record from a non-default source. For instance, instead of using untyped labels for iris organisms as Tutorial: Features & labels, we can use the ncbitaxon ontology:

source = bt.Source.get(entity="bionty.Organism", name="ncbitaxon")
source

Source(uid='4tsk', entity='bionty.Organism', organism='all', name='ncbitaxon', version='2023-06-20 00:00:00 ', in_db=False, currently_used=True, description='NCBItaxon Ontology', url='s3://bionty-assets/df_all__ncbitaxon__2023-06-20__Organism.parquet', md5='00d97ba65627f1cd65636d2df22ea76c', source_website='https://github.com/obophenotype/ncbitaxon', created_by_id=1, created_at=2024-10-29 21:22:29 UTC)

# validate against the NCBI Taxonomy
bt.Organism.validate(["iris setosa", "iris versicolor", "iris virginica"], source=source)

records = bt.Organism.from_values(
    ["iris setosa", "iris versicolor", "iris virginica"], source=source
)

# since we didn't seed the Organism registry with the NCBITaxon public ontology
# we need to save the records to the database
ln.save(records)

# now we can query a iris organism and view its parents and children
iris = bt.Organism.get(name="iris")
iris.view_parents(with_children=True)
