🚀 Quick Start

30-Second Demo

# Install
pip install rxnextract

# Use
python -c "
from chemistry_llm import ChemistryReactionExtractor
extractor = ChemistryReactionExtractor.from_pretrained('chemplusx/rxnextract-complete')
procedure = 'Add 5g NaCl to 100mL water and stir for 30 minutes at room temperature.'
results = extractor.analyze_procedure(procedure)
print('Reactants:', results['extracted_data']['reactants'])
print('Conditions:', results['extracted_data']['conditions'])

🔑 Quick Examples

Basic Usage

from chemistry_llm import ChemistryReactionExtractor

# Initialize extractor
extractor = ChemistryReactionExtractor.from_pretrained("chemplusx/rxnextract-complete")

# Analyze procedure
procedure = """
Dissolve 5.0 g of benzoic acid in 100 mL of hot water.
Add 10 mL of concentrated HCl and cool the solution.
Filter the precipitated product and wash with cold water.
"""

results = extractor.analyze_procedure(procedure)
print(results['extracted_data'])

Command Line Interface

# Interactive mode
rxnextract --interactive

# Batch processing
rxnextract --input procedures.txt --output results.json

# Single procedure
rxnextract --procedure "Add 2g NaCl to 50mL water"

Analysis & Research

from chemistry_llm.analysis import ErrorAnalyzer, AblationStudy

# Error analysis
analyzer = ErrorAnalyzer()
error_results = analyzer.analyze_prediction_errors(predictions, ground_truth)

# Ablation study
ablation = AblationStudy(model_path="./model")
study_results = ablation.run_complete_study(test_data, ground_truth)

🏗️ System Requirements

Component	Minimum	Recommended
