phasorpy/phasorpy: v0.6

PhasorPy is an open-source Python library for the analysis of fluorescence lifetime and hyperspectral images using the phasor approach.

This is the sixth alpha release of the PhasorPy library. It contains several bug fixes, improvements, and breaking changes.

The new phasor_component_fit function fits fractions of multiple components to phasor coordinates. The phasor_nearest_neighbor function returns nearest neighbors in phasor coordinates. The phasor_to_normal_lifetime function returns single lifetimes closest to phasor coordinates. The phasor_semicircle_intersect function returns intersections of lines with the universal semicircle.

The LifetimePlots class interactively plots lifetimes in the time domain, frequency domain, and phasor plot. It can be invoked from the command line with python -m phasorpy lifetime.

The two_fractions_from_phasor and graphical_component_analysis functions are renamed to phasor_component_fraction and phasor_component_graphical, respectively. The versions function has moved to the phasorpy.utils namespace. The spectral_vector_denoise, anscombe_transform, and anscombe_transform_inverse functions have moved to the phasorpy.experimental namespace.

Functions in the io module now return only the first channel by default.

Three new tutorials are added: "Geometrical interpretation of lifetimes", "Multi-component fit", and "FRET efficiency image". This release supports Python 3.11 to 3.13.
