PartSeg

PartSeg is a GUI and a library for segmentation algorithms. PartSeg also provide napari plugins for IO and labels measurement.

This application is designed to help biologist with segmentation based on threshold and connected components.

Installation

• From binaries:

  • Windows (build on Windows 10)
  • Linux (build on Ubuntu 18.04)
  • MacOS (build on MacOS Mojave)

• With pip:

  • From pypi: pip install PartSeg[all]
  • From repository: pip install git+https://github.com/4DNucleome/PartSeg.git

Installation troubleshooting information could be found in wiki: wiki. If this information does not solve problem you can open issue.

Running

If you downloaded binaries, run the PartSeg (or PartSeg.exe for Windows) file inside the PartSeg folder

If you installed from repository or from pip, you can run it with PartSeg command or python -m PartSeg. First option does not work on Windows.

PartSeg export few commandline options:

• --no_report - disable error reporting
• --no_dialog - disable error reporting and error dialog. Use only when running from terminal.
• segmentation_analysis - skip launcher and start analysis gui
• segmentation - skip launcher and start segmentation gui

napari plugin

PartSeg provides napari plugins for io to allow reading projects format in napari viewer.

Save Format

Saved projects are tar files compressed with gzip or bz2.

Metadata is saved in data.json file (in json format). Images/masks are saved as *.npy (numpy array format).

Interface

Launcher. Choose the program that you will launch:

Main window of Segmentation Analysis:

Main window of Segmentation Analysis with view on measurement result:
