Features

• Fast Binary Parsing: Optimized parsing with NumPy and PyArrow (0.1-1 sec/file)
• Complete Metadata: Extract instrument settings, sample info, and experimental conditions
• Baseline Correction: Automatic baseline subtraction with validation
• DTG Analysis: Derivative thermogravimetry calculation with smoothing options
• Batch Processing: Parallel processing of multiple files
• Data Export: Convert to Parquet, CSV, and JSON formats
• CLI Support: Command-line interface for automation

Installation

pip install pyngb

Quick Example

from pyngb import read_ngb
import polars as pl
import json

# Load NGB file with embedded metadata
table = read_ngb("experiment.ngb-ss3")
df = pl.from_arrow(table)

# Access data
print(f"Loaded {df.height} data points")
print(f"Temperature range: {df['sample_temperature'].min():.1f} to {df['sample_temperature'].max():.1f} °C")

# Access metadata
metadata = json.loads(table.schema.metadata[b'file_metadata'])
print(f"Sample: {metadata.get('sample_name', 'Unknown')}")

# Baseline correction
corrected = read_ngb("sample.ngb-ss3", baseline_file="baseline.ngb-bs3")

# DTG analysis
from pyngb.api.analysis import add_dtg
table_with_dtg = add_dtg(table, method="savgol", smooth="medium")

Command Line Usage

# Convert single file
python -m pyngb sample.ngb-ss3

# Batch processing with baseline correction
python -m pyngb *.ngb-ss3 -b baseline.ngb-bs3 -f parquet -o ./processed/

# Get help
python -m pyngb --help
