Summary

Load and parse molecular fingerprint vectors from biosynfoni datasets (e.g., Zenodo deposits) into memory for downstream statistical and similarity analysis. This skill enables extraction of fingerprint bit patterns and metadata required for characterizing molecular representation properties.

When to use

When you have deposited or archived biosynfoni fingerprint vectors (such as from Zenodo 10.5281/zenodo.14822624) and need to ingest them into a Python workflow to compute distributional statistics, bit-frequency profiles, sparsity metrics, or pairwise similarity coefficients. Trigger this skill when beginning a fingerprint characterization or validation study.

When NOT to use

• Fingerprint vectors are already loaded in memory or pre-computed in a feature matrix; use this skill only for initial ingestion from archived deposits.
• Input is a pre-processed feature table or descriptor matrix in non-fingerprint format (e.g., physicochemical properties, continuous descriptors).
• Fingerprints are in a non-biosynfoni format (e.g., Morgan, ECFP, structural keys); use format-specific parsers instead.

Inputs

• Zenodo dataset deposit identifier (DOI or record ID)
• biosynfoni package installation
• Python 3.9+ environment

Outputs

• In-memory fingerprint vector matrix (2D array, molecules × bits)
• Vector metadata (molecule identifiers, bit count, sparsity per vector)
• Dataset shape and integrity report

How to apply

Install biosynfoni in development mode using pip install -e .[dev] from the project root. Load all fingerprint vectors from the Zenodo dataset deposit (10.5281/zenodo.14822624) using biosynfoni's data-loading API. Verify that the loaded vectors are in-memory as a 2D array or matrix structure (rows = molecules, columns = fingerprint bit positions). Confirm vector dimensionality and bit-depth match the biosynfoni specification for the dataset. Validate that no null or malformed vectors are present before proceeding to bit-frequency or similarity computations.

• RDKit (Dependency for biosynfoni; handles molecular parsing and structure representation required for fingerprint loading pipelines)

Examples

from biosynfoni import Biosynfoni; from rdkit import Chem; mol = Chem.MolFromSmiles('C1=CC=CC=C1'); fp = Biosynfoni(mol).fingerprint

Evaluation signals

• Loaded fingerprint matrix has expected shape (N molecules × M bits) matching the Zenodo deposit metadata.
• All fingerprint vectors are bit-arrays with integer or binary values; no null, NaN, or non-numeric entries present.
• Vector count matches the number of unique molecules declared in the dataset deposit.
• Bit-frequency distribution across all positions is non-zero (i.e., at least one molecule has a set bit at each position, or sparsity profile is consistent with natural product chemistry expectations).
• Spot-check: manually verify that a subset of 5–10 fingerprints can be reconstructed or re-computed from source molecules using Biosynfoni(mol).fingerprint.

Limitations

• Loading performance scales linearly with deposit size; very large Zenodo datasets (>1M molecules) may require streaming or batch processing rather than full in-memory load.
• biosynfoni requires Python 3.9+; older environments may fail at installation.
• No changelog documented for biosynfoni versions; reproducibility across versions is not guaranteed without pinning a specific release.
