PyPI version License CI Status Coverage Documentation Status

Fractal tasks core is the reference task package for the Fractal framework. It provides a collection of ready-to-use tasks for processing bioimaging data, including OME-Zarr conversion, image registration, and illumination correction.

Fractal_overview_small

Fractal is a framework developed at the BioVisionCenter to process bioimaging data at scale in the OME-Zarr format and prepare the images for interactive visualization.

Available Tasks

For a complete list of all available Fractal tasks (including tasks from other packages), visit the Fractal task list.

This package includes the following tasks:

  • Image Processing:

    • Project Image (HCS Plate): Generates intensity projections (e.g., maximum intensity projection) for images in an HCS plate.
    • Illumination Correction: Applies flatfield correction and background subtraction using pre-calculated illumination profiles.

  • Registration:

    • Calculate Registration (image-based): Computes translations for aligning images in multiplexed image analysis.
    • Find Registration Consensus: Generates consensus transformations for aligning multiple acquisitions, updating ROI tables as necessary.
    • Apply Registration to Image: Applies registration to images based on existing or newly created ROI tables.

  • Other Utilities:

    • Import OME-Zarr: Validates and processes existing OME-Zarr files, adding ROI tables and metadata for further processing in Fractal.

Installation

pip install fractal-tasks-core

If you collect this package on Fractal server to run the tasks, make sure to use the package name fractal-tasks-core in the corresponding field.
