Navigating data ontologies

Tip

Open this tutorial in Google colab for interactive viewing.

# @title Install AlphaGenome

# @markdown Run this cell to install AlphaGenome.
from IPython.display import clear_output
! pip install alphagenome
clear_output()

Setup and imports

from alphagenome.models import dna_client
from google.colab import data_table
import pandas as pd
from google.colab import userdata

data_table.enable_dataframe_formatter()

Interactively view output metadata

First, we load the model.

dna_model = dna_client.create(userdata.get('ALPHA_GENOME_API_KEY'))

output_metadata = dna_model.output_metadata(
    dna_client.Organism.HOMO_SAPIENS
).concatenate()

Click Filter on the upper right hand side of the interactive dataframe and type a cell or tissue name like “brain” into the Search by all fields box to find the ontology_curie term corresponding to a tissue and output type of interest:

How many tracks are there per output type?

# Count human tracks
human_tracks = (
    dna_model.output_metadata(dna_client.Organism.HOMO_SAPIENS)
    .concatenate()
    .groupby('output_type')
    .size()
    .rename('# Human tracks')
)

# Count mouse tracks
mouse_tracks = (
    dna_model.output_metadata(dna_client.Organism.MUS_MUSCULUS)
    .concatenate()
    .groupby('output_type')
    .size()
    .rename('# Mouse tracks')
)

pd.concat([human_tracks, mouse_tracks], axis=1).astype(pd.Int64Dtype())

	# Human tracks	# Mouse tracks

OutputType.ATAC	167	18
OutputType.CAGE	546	188
