      This is data that was originally processed through
      https://github.com/cmatKhan/callingCardsTools/ and stored (including some
      more processing) in https://github.com/cmatKhan/yeastregulatorydb. It is
      the data that was used for the QC and filtering decisions in the 2026
      modeling paper. In general, unless you are trying to exactly replicate the
      2026 modeling paper, you should use the 2026_analysis_set for analysis
      that uses the published results. Or, to use data that can be reproduced
      directly from the genome_map data, `annotated_feature_reprocess_*`. The
      suffix indicates which promoter set was used  to generate the results from
      the genome_map data.

    description: >-
      For the 2026 modeling paper, we labeled replicates passing if it has
      `>=`3k hops and DTO `<=` 0.01 in either kemmeren or hackett. For a TF with
      more than 1 passing replicate, a combined sample is created by summing the
      hops across the passing replicates. This is the data that is used for the
      2026 modeling paper as predictors. It is retained here for replication and
      transparency, but we do not recommend using it for new analysis. Instead,
      to use the published results, use the `2026_analysis_set` which includes
      the same combined samples, but also includes the passing single
      replicates. Otherwise, the annotated_feature_reprocess_*_analysis datasets
      are more directly reproducible from the genome_map data, using a specified
      promoter set, and have combined samples using the same logic.

      This dataset is the dataset that was used in the 2026 modeling paper. A
      passing  replicate has >=3000 hops had a dto empirical pvalue < 0.01
      against either kemmeren or hackett. Where a given regulator had multiple
      passing replicates, those replicates were combined (see
      annotated_feature_combined). This dataset should be used when you want to
      use the published results from the 2026 modeling paper. If you want to use
      data that can be reproduced directly from the genome_map data included in
      this repo, especially when called against different promoter sets, then
      use the annotated_feature_reprocess_*_analysis datasets.

      Calling Cards annotated features reprocessed from the genome_map data
      using scripts/quantify_regions.R against the yiming promoters in
      BrentLab/yeast_genome_resources. This is very nearly exactly the same as 
      annotated_features, though there may be some differences around the
      boundaries  (intentional), and this includes higher numeric resolution in
      the most significant promoters by using hte log argument in the poisson
      distribution function.

      hops had a dto empirical pvalue < 0.01 against either kemmeren or hackett.
      Where a given regulator had multiple passing replicates, those replicates
      were combined (see annotated_feature_combined). This dataset should be
      used when you want to use data that can be reproduced directly from the
      genome_map data included in this repo, using the mindel promoter
      definitions. See scripts/quantify_regions.R as well as

Calling Cards

This is data produced in both the Brent Lab and Mitra Lab at Washington University.

Accessing Data

The examples below require labretriever (pip install labretriever) and/or the HuggingFace Hub client (pip install huggingface_hub).

Accessing Data with labretriever

This repository is part of a collection configured as a unified database using labretriever.VirtualDB. Download the collection config and use it to query the data directly in Python, or with an AI assistant using the labretriever plugin.

from labretriever.virtual_db import VirtualDB
from labretriever.datacard import DataCard

# Citation and metadata
card = DataCard("BrentLab/callingcards")
print([c.config_name for c in card.configs])  # list available datasets

# print citation
info = card.info()
print(info["citation"])

# path to the downloaded brentlab_yeast_collection.yaml
vdb = VirtualDB("/path/to/brentlab_yeast_collection.yaml")

print(vdb.get_dataset_description("callingcards"))
vdb.query("SELECT * FROM callingcards LIMIT 5")

Direct parquet access

The repository contains more data than what is exposed through the collection configuration. Use DataCard.info() to inspect available files, then download and query with DuckDB.

Some files are single parquet files (e.g. metadata files); others are partitioned datasets. Download a metadata file first to identify relevant partitions before fetching the full data.

Single parquet file example:

from huggingface_hub import snapshot_download
import duckdb

repo_path = snapshot_download(
    repo_id="BrentLab/callingcards",
    repo_type="dataset",
    allow_patterns="annotated_feature_meta.parquet",
)
conn = duckdb.connect()
# returns a pandas DataFrame with the first 5 rows
conn.execute(
    "SELECT * FROM read_parquet(?) LIMIT 5",
    [f"{repo_path}/annotated_feature_meta.parquet"],
).df()

Partitioned dataset example (the annotated_feature directory):

repo_path = snapshot_download(
    repo_id="BrentLab/callingcards",
    repo_type="dataset",
    allow_patterns="annotated_feature/**",
)
conn.execute(
    "SELECT * FROM read_parquet(?) LIMIT 5",
    [f"{repo_path}/annotated_feature/**/*.parquet"],
).df()

Accessing using R

Clone the repository and read parquet files directly with arrow:

# install.packages("arrow")
arrow::read_parquet("annotated_feature_meta.parquet")
