v1.2.5#

We are pleased to announce the release of the minor update version v1.2.5.

This release focuses on performance improvements, new functionality, and a number of bug fixes across boundary handling, network cropping, and query behavior.

Features#

  • Labeled TIFF support:

    • Added segmentation_mask_to_domain for converting labeled TIFF files into MuSpAn domains.

    • Added a small TIFF-to-dataset example to help demonstrate the workflow.

  • Version string support:

    • Added a version string to the package for easier version tracking.

  • Expanded query and network functionality:

    • Added more efficient similarity-weight-to-edge and network-based query handling.

    • print labels and print collections now return DataFrames.

Performance Improvements#

  • Vectorised geometry operations:

    • Polygon distance calculations have been vectorised.

    • Point-to-line distance calculations have been optimised.

    • point in poly operations have been accelerated using Cython.

  • Improved spatial and neighbourhood computations:

    • cluster_neighbourhoods has been optimised for continuous labels.

    • Moran’s I and Getis-Ord calculations have been improved for both adjacency lookup and memory usage.

    • adjacency_permutation_test has been optimised.

  • Boundary and shape handling:

    • update_circle_boundaries received a small optimisation.

    • Boundary shape reconstruction has been improved when rebuilding from updated boundaries.

Bug Fixes#

  • Crop domain and network handling:

    • Fixed updating of networks following clipping.

    • Fixed frozen graphs in crop domain operations following deepcopy.

    • Added a test for cropping domains with networks.

  • Query and colour bar handling:

    • Fixed duplicate collection entries in queries.

    • Improved edge weight queries to minimise duplicates in the special case where this is required.

    • Fixed null colour bar handling.

  • Plotting:

    • Fixed plotting of PCF confidence intervals.

Maintenance#

  • Merged several upstream branches and internal fixes.

  • Updated the package version number to 1.2.5.
