skan v0.12.2

This minor release added an important bug fix from Neil Shephard (#235), preventing a crash when working with float32 images.

skan v0.12.1

This minor release fixed issues with the version switcher in the documentation.

skan v0.12.0

This release adds NumPy 2.0 compatibility (while remaining compatible with 1.x) (#229). It also lays the groundwork for new skeleton editing features with bidirectional Skeleton to NetworkX conversion functions (#224.

We also have a minor deprecation that should improve quality of life in the future: column names in the summary dataframe can now use _ as the separator (instead of -), which allows one to use the pandas attribute access for columns (for example, summary.branch_distance instead of summary['branch-distance']. Use the separator='_' keyword argument to summarize to take advantage of this feature (which will become the default in a future version), or separator='-' to maintain the current behavior even when new versions come out (#215).

The napari plugin now lets you make a Shapes layer fully backed by a Skeleton dataset, including coloring the edges by features in the summary table (#201).

Thanks to Neil Shephard, James Ryan, Jarod Hanko, and Tim Monko for their contributions to this release! 🙏 You can find the full list of changes below:

API changes

  • #215: The separators used for column names are configurable, and will transition to _ in the future. This is to make it easier to use the dataframe attribute interface, e.g. summary.branch_distance

New features

  • #229: NumPy 2 compatibility
  • #224: Create a networkx summary graph from a Skeleton
  • #201: Add napari widget to generate shapes layer from a skeletonized label layer

Improvements

  • #220: Allow mean pixel value calculation from integer values, not just floats
  • #212: Improved error reporting and tests for prune_paths methods

Bug fixes

  • #221: Fix documentation builds
  • #210: Cache skeleton_image shape for use by the path_label_image method

Documentation
