PyIgor

PyIgor facilitates communication between Python and WaveMetrics Igor Pro, enabling seamless data and command exchange.

Requirements

• Igor Pro 7.0 or later: Ensure you have Igor Pro 7.0 or a newer version installed.
• HDF5 XOP: Install the HDF5 XOP module. Detailed installation instructions are available in the "HDF5 installation" section under Igor Pro's help topics.
• PyIgor Procedure File: Download the pyigor.ipf file from GitHub and place it in the Igor Procedures folder for convenience.

Installation

To install PyIgor, use the following pip command:

pip install pyigor

Usage

Accessing Igor Pro from Python

Here’s how you can interact with Igor Pro using PyIgor:

from pyigor import Connection
import numpy as np

# Establish a connection with Igor Pro
igor = Connection()

# Send a numpy array to Igor Pro
array = np.sin(np.linspace(0, 10, 100))
igor.put(array, "sinwave")

# Execute a command in Igor Pro
igor("sinwave += 1")

# Retrieve a wave from Igor Pro
wv = igor.get("sinwave")
print(wv.array)

Accessing Python from Igor Pro

Preparing Python

from pyigor import Connection

# Establish a connection
igor = Connection()

# Register a function callable from Igor Pro
@igor.function 
def myfunc(a):
    return a * a

# Keep the connection open; not required in interactive mode
igor.wait_done()

Use the Connection(security_hole=True) to call any Python code from Igor Pro. This setting allows executing Python code through HTTP requests to http://localhost/code using eval(code). Important: Use this option only if you understand the security implications.

Calling Python Functions from Igor Pro

Execute Python functions registered via PyIgor from Igor Pro:

print PyIgorCall("myfunc(10)")

Security Note

When enabling security_hole=True, ensure your environment is secure and understand the risks associated with executing arbitrary code.
