ndslice 0.1.1

Interactive N-dimensional numpy array viewer with FFT support

ndslice

Interactive N-dimensional array viewer with FFT support for NumPy arrays.

Features

• N-dimensional slicing: View any 2D slice of your N-dimensional data
• Multiple view modes: Image view and line plot modes
• FFT/IFFT support: Apply Fourier transforms along any dimension with a click
• Complex data support: View real, imaginary, magnitude, or phase components
• Scale transformations: Linear and symmetric logarithmic scaling
• Interactive controls: Mouse hover for pixel values, dynamic zooming, and panning

Installation

From PyPI

pip install ndslice

From source

git clone https://github.com/henricryden/ndslice.git
cd ndslice
pip install -e .

Usage

Basic Usage

The ndslice() function opens an interactive window to explore your N-dimensional arrays:

from ndslice import ndslice
import numpy as np

# View a 4D array
data_4d = np.random.randn(10, 20, 30, 40)
ndslice(data_4d)

# View complex FFT data
fft_data = np.fft.fftn(data_4d)
ndslice(fft_data, title='FFT Data')

Interactive Features

• Dimension Selection: Click Y/X buttons to choose which dimensions to display
• Slicing: Use spinboxes to select the slice index for other dimensions
• FFT Transforms:
  • Left-click dimension labels to apply FFT
  • Right-click to apply inverse FFT
  • Click again to return to native domain
• Channel Selection (for complex data): Real, Imaginary, Magnitude, or Phase
• Scale Options: Linear or Symmetric Log scaling
• Display Modes: Square pixels, square FOV, or fit to window
• View Modes: Switch between 2D image view and 1D line plot
• Complex Data: View real, imaginary, magnitude, or phase components

Requirements

• Python >= 3.8
• NumPy >= 1.20.0
• PyQtGraph >= 0.12.0
• PyQt5 >= 5.15.0
