dda-py 0.2.0

Python wrapper for DDA with APE (Actually Portable Executable) binary support

dda-py: Python Wrapper for Delay Differential Analysis

A Python wrapper for DDA with native support for APE (Actually Portable Executable) binaries, enabling cross-platform execution without platform-specific binaries.

Features

• APE Binary Support: Native support for Actually Portable Executable binaries
• Cross-Platform: Works on Windows, macOS, and Linux with the same APE binary
• Async Support: Both synchronous and asynchronous execution
• Easy Integration: Simple Python API for DDA analysis

Installation

Install the package from PyPI:

pip install dda-py

Usage

Basic Usage

import dda_py

# Initialize with APE binary path
dda_py.init("./run_DDA_AsciiEdf")

# Run DDA analysis
Q, output_path = dda_py.run_dda(
    input_file="data.edf",
    channel_list=["1", "2", "3"]
)

print(f"Result shape: {Q.shape}")  # channels × time windows

Using DDARunner Class

from dda_py import DDARunner

# Create runner instance
runner = DDARunner("./run_DDA_AsciiEdf")

# Run analysis with options
Q, output_path = runner.run(
    input_file="data.edf",
    channel_list=["1", "2", "3"],
    bounds=(1000, 5000),  # Optional time bounds
    cpu_time=True         # Enable CPU timing
)

Async Usage

import asyncio
from dda_py import DDARunner

async def analyze_data():
    runner = DDARunner("./run_DDA_AsciiEdf")
    Q, output_path = await runner.run_async(
        input_file="data.edf",
        channel_list=["1", "2", "3"]
    )
    return Q

# Run async
result = asyncio.run(analyze_data())

APE Binary Support

This package is designed to work with APE (Actually Portable Executable) binaries. APE binaries:

• Run on Windows, macOS, and Linux without modification
• No need for platform-specific binaries
• Automatic platform detection and execution

The package automatically handles APE binary execution across different platforms using the appropriate shell interpreter when needed.

Requirements

• Python 3.6+
• NumPy >= 1.19.0
• DDA APE binary (place in your working directory)
