Thyra

Tests PyPI Python 3.12+ License: MIT Code style: black Docs

Thyra (from Greek thyra, meaning "door" or "portal") -- a modern Python library for converting Mass Spectrometry Imaging (MSI) data into the standardized SpatialData/Zarr format, serving as your portal to spatial omics analysis workflows.

Try it without any data

pip install thyra
thyra-example-data example_data/synthetic_brain.imzML   # generates a small synthetic dataset
thyra example_data/synthetic_brain.imzML example_data/synthetic_brain.zarr

See the Tutorial for a full walkthrough, including the published example dataset (10.5281/zenodo.18326569).

Features

  • Multiple Input Formats: ImzML, Bruker (.d directories), Waters (.raw directories)
  • SpatialData Output: Modern, cloud-ready format with Zarr backend
  • Memory Efficient: Handles large datasets (100+ GB) through streaming processing
  • Optical Alignment: Automatic MSI-to-optical image registration for Bruker data
  • Multi-Region Support: Handles slides with multiple tissue sections
  • Resampling: Physics-aware mass axis resampling (enabled by default)
  • 3D Support: Process volume data or treat as 2D slices
  • Cross-Platform: Windows, macOS, and Linux

Installation

pip install thyra

Quick Start

Command Line

# Basic conversion (resampling enabled by default)
thyra input.imzML output.zarr

# Bruker data with verbose logging
thyra data.d output.zarr -v DEBUG

# Disable resampling
thyra input.imzML output.zarr --no-resample

Python API

from thyra import convert_msi

success = convert_msi("data/sample.imzML", "output/sample.zarr")

Working with the Output

import spatialdata as sd

sdata = sd.read_zarr("output/sample.zarr")
msi_table = sdata.tables["msi_dataset_z0"]

print(f"Shape: {msi_table.shape}")  # (pixels, m/z bins)
print(f"m/z range: {msi_table.var['mz'].min():.1f} -- {msi_table.var['mz'].max():.1f}")
