• Changelog

Changelog (nionswift-eels-analysis)

0.5.4 (2021-05-26):

• Maintenance to reduce dependency on new/unstable niondata features.

• Improve colors for better visibility in align ZLP, live ZLP, live thickness.

• Vectorize thickness mapping for significant speed-up.

• Add calibrate spectrum tool.

0.5.3 (2021-03-12):

• Fix issue with Align ZLP (COM) when using it on empty data.

• Fix issue with Align ZLP (COM) that caused a bias towards half-integer shifts.

• Allow Align ZLP to be used on single spectra. Useful for bringing the ZLP to calibrated zero.

0.5.2 (2020-11-13):

• Fix issue with single channel zero loss peaks in thickness calculation.

• Ensure default background is power law.

• Improve wording in background menu.

0.5.1 (2020-10-06):

• Add exponential functions for two-area method.

• Add two-area background fitting class.

• Improve speed of polynomial background and fix power law.

0.5.0 (2020-08-31):

• Rework background models to allow for plug-in models.

• Made Align ZLP output the measured shifts in addition to the aligned spectra.

• Allow graphics to select the ROI for aligning spectra in Align ZLP.

• Allow 2D images in Align ZLP and interpret y-axis as sequence axis.

• Reworked Align ZLP to eliminate duplicate code.

0.4.4 (2019-10-24)

• Changed shift method in ZLP subpixel align to scipy.ndimage.shift with linear interpolation to get rid of artifacts.

0.4.3 (2019-04-29)

• Added checks to avoid applying live ZLP and thickness to 2D data items.

• Moved ZLP analysis functions to nion.eels_analysis module for better reuse.

0.4.2 (2019-03-27)

• Make Align ZLP support sequences AND 1D collections.

• Added menu items for center-of-mass and gaussian fit for ZLP alignment (both do sub-pixel alignment but much faster than cross-correlation)

0.4.1 (2019-01-07)

• Improve data type handling (do not auto-promote to float64).

• Improve menu item layout.

0.4.0 (2018-12-21)

• Add menu items for live thickness, thickness mapping, align zlp.

0.3.0 (2018-12-12)

• Nion Swift 0.14 compatibility.

• Use composite line plot display for display again.

0.2.1 (2018-10-14)

• Update original background subtraction to not use deprecated composite library item.

0.2.0 (2018-09-28)

• Add simplified background subtraction.

• Add live ZLP tracking.

0.1.1 (2018-05-12)

• Initial version online.
