magtrack 0.7.4

Convert images of beads into XYZ positions

MagTrack is a free open-source Python library for tracking symmetric beads in single-molecule magnetic tweezers experiments.

• Sub-pixel XYZ coordinates
• GPU accelerated (optional, requires a CUDA-capable GPU)
• Python notebook included with examples
• Documented, tested, and benchmarked
• Only depends on NumPy, SciPy, and CuPy
• Runs on Windows, macOS, and Linux
• Easy installation with pip

⏳ Install

Get started with MagTrack by following the installation instructions.

⚒ Usage

import magtrack

# Run the full default XYZ pipeline
x, y, z, profiles = magtrack.stack_to_xyzp(stack)

# Or make your own pipeline from algorithms you prefer
x, y = magtrack.center_of_mass(stack)
x, y = magtrack.auto_conv_sub_pixel(stack, x, y)
profiles = magtrack.fft_profile(stack)
