chemprep 0.1.0

A Python library for molecular fingerprinting and similarity calculations.

ChemPrep

A Python library and command-line tool for molecular fingerprinting, similarity calculations, and descriptor generation using RDKit.

Installation

pip install chemprep

Usage

As a Library

from chemprep.fingerprints import generate_fingerprint, get_available_fingerprints
from chemprep.similarity import calculate_similarity, get_available_similarity_metrics
from chemprep.descriptors import get_all_descriptors

# Get available fingerprints and similarity metrics
print(get_available_fingerprints())
print(get_available_similarity_metrics())

# Generate a fingerprint
smiles = "CCO"
fp = generate_fingerprint(smiles, fingerprint_type="Morgan")
print(fp)

# Calculate similarity
smiles1 = "CCO"
smiles2 = "CCN"
similarity = calculate_similarity(smiles1, smiles2, fingerprint_type="Morgan", similarity_metric="Tanimoto")
print(similarity)

# Generate descriptors
descriptors = get_all_descriptors(smiles)
print(descriptors)

Command-Line Interface

# Get help
chemprep --help
chemprep fingerprint --help
chemprep similarity --help
chemprep descriptors --help

# Generate a fingerprint for a single SMILES
chemprep fingerprint "CCO"

# Generate fingerprints from a file
chemprep fingerprint -i smiles.txt -t RDKit -o fingerprints.csv

# Calculate similarity
chemprep similarity "CCO" "CCN" -t Morgan -m Tanimoto

# Generate descriptors for a single SMILES
chemprep descriptors "CCO"

# Generate descriptors from a file
chemprep descriptors -i smiles.csv -o descriptors.csv
