A plugin for collaborative annotation in cryoET using copick

---

This napari plugin was generated with Cookiecutter using @napari's cookiecutter-napari-plugin template.

Installation

You can install napari-copick via pip:

pip install napari-copick

To install latest development version:

pip install git+https://github.com/copick/napari-copick.git

Usage

Using a copick config file

napari-copick run --config path/to/copick_config.json

Using dataset IDs from CZ cryoET Data Portal

napari-copick run --dataset-ids 10440 10441 --overlay-root /path/to/overlay_root

You can specify multiple dataset IDs separated by spaces.

GUI Usage

The plugin provides an intuitive interface with two loading options:

1. Load Config File: Opens a file dialog to select a copick configuration JSON file
2. Load from Dataset IDs: Opens a dialog to enter CZ cryoET Data Portal dataset IDs and overlay root path

After loading, you'll see a hierarchical tree of the project structure that you can navigate to access tomograms, segmentations, and picks.

Tomogram Handling

napari-copick now handles multiscale zarr arrays directly:

• Automatically detects and loads all available resolution levels
• Creates a proper multiscale image stack using napari's native multiscale API
• Uses dask for efficient lazy loading of large tomogram data
• Applies appropriate scaling factors based on the voxel size metadata

This direct zarr handling provides better performance and more flexibility compared to relying on external plugins.
