ezDIC v0.1.3

Poisson ratio export and GUI workflow update

This release adds a direct Poisson-ratio export workflow for users who define one axial ROI group and one transverse ROI group. It also makes the main analysis action more visible for new users.

DOI: 10.5281/zenodo.20222465

What changed

  • Added ROI group roles: none, axial, and transverse.
  • Added Poisson-ratio calculation from engineering strain:
    PoissonRatio = - TransverseEngineeringStrain / AxialEngineeringStrain.
  • Added AxialEngineeringStrain, TransverseEngineeringStrain, and PoissonRatio columns to strain_all_groups.txt when axial/transverse roles are set.
  • Added poisson_ratio.txt and poisson_ratio.png exports when axial/transverse roles are set.
  • Kept failed tracking frames, missing strain values, and near-zero axial strain as NaN in Poisson-ratio output.
  • Improved the right-side GUI workflow area with a compact first-screen layout, a clearer five-step beginner guide, hover tips for key workflow buttons, a prominent start button, and a separate run-status section.
  • Disabled the start button during processing to reduce accidental duplicate runs.
