pandorica 1.0.0

Analytical tools for cryo-electron microscopy (stitching + napari validator).

PANDORICA

Analytical tools for electron microscopy.

Bundled tools

• pandorica.stitch — serial-section tomogram stitcher: MT-graph-driven alignment with an image-only fallback, diffeomorphism-guarded TPS warp, global pose solve, CPU/GPU volume export. See pandorica/stitch/README.md for the method and related-work references.
• pandorica.napari — napari plugin: visually validate the stitcher on real datasets and record coarse-alignment ground truth by hand.

Install

pip install pandorica                # core stitcher + CLI
pip install "pandorica[napari]"      # add the napari validator widgets

Use

python -m pandorica.stitch.cli <input_dir>

from pandorica.stitch.cli import run_stitch
run_stitch("path/to/sections")       # writes <input_dir>/stitched_output/

If tardis_em is also installed, the same entry point is exposed as the tardis_stitch console script.
