Release 2.0.4 : fitting with IRF

This release sees one major change:

• Added the function with_irf, which allows to modify fitting functions to include the effects of instrument response.

Other changes:

• Added support for crystals.ElectronicStructure. This requires crystals version 1.1.0 and up.
• Various documentation fixes.

Release 2.0.2 : Minor improvements

• Added theSelection class and RectSelection, DiskSelection, RingSelection, and
  ArbitrarySelection to assemble time-series. This is a generalization of iris-ued's time-series rects.
• Added real-time pixel value and cursor position to skued.diffshow.
• Added indices_to_text, a plotting utility function to render Miller indices to Mathjax/LaTeX-style text (Matplotlib-compatible).

2.0.1: minor bug fixes

This release sees two minor bug fixes:

• skued.diffshow will temporarily switch PyQtGraph's image axis order to the row-major, which is a saner default.
• Fixed an issue where a typo in electron_velocity would raise an exception.

There is also a new way to quickly look at images:

• Added skued command-line utilities. Images can be shown (with interactive viewer) using skued diffshow [path].
  Crystal information can be determined using skued crystinfo [path].

Release 2.0.0: breaking changes

scikit-ued's success has propagated through the Python community:

• Broke off the skued.structure subpackage into its own library, crystals.
• Removed masked_register_translation in favour of the new scikit-image implementation ported from scikit-ued.

Due to a conflict between scikit-image and scikit-ued conventions, some breaking changes are required.
Image conventions will now follow that of scikit-image. Most importantly:

• Changed the convention on image masks to align with the scikit-image convention. Masks will be True for valid pixels, and False on invalid pixels.

We took the opportunity to make other breaking changes:

• Removed xcorr and mnxc as these were the backbone of masked_register_translation and are no longer needed.
• Added aspherical electron form factor parametrization from Zheng et al. 2009.
• Removed diff_register in favor of an analog of scikit-image's register_translation and masked_register_translation.
• Removed powder_center due to unpredictable performance.
• Removed calibrate_scattvector, which was deprecated.
• Removed time_shift and time_shifts, which were deprecated.
• Removed shift_image in favor of scipy.ndimage.shift.
• bounded_reflections has been removed in favor of Crystal.bounded_reflections in the crystals library (version >= 0.6.4)

We have also added some features:

• Added the patterson function to calculate Patterson pair-pair distribution functions from polycrystalline diffraction patterns.
• Added the detector_scattvectors function to determine the wavevectors visible on a detector, in transmission, based on experimental geometry.

For iris-ued users

Be sure to update to iris-ued 5.1.3. Older versions don't have an upper bound on scikit-ued. iris-ued verisions < 5.1.4 only support scikit-ued 1.*

Pre-release 2.0.0 alpha 1

• Removed xcorr and mnxc as these were the backbone of masked_register_translation and are no longer needed.
• Broke off the skued.structure package into its own library, crystals. The API is still provided under skued.structure for now.
• Added aspherical electron form factor parametrization from Zheng et al. 2009.
• Removed diff_register in favor of an analog of scikit-image's register_translation and masked_register_translation.
• Removed powder_center due to unpredictable performance. Warnings will be issued on every function call. It will be removed in an upcoming release
• Removed calibrate_scattvector, which was deprecated.

Release 1.0.1.1 : time-series fitting

Fitting of intensity time-series was added.

Some bugs concerning tests and temporary files were also fixed.

1.0.1.0 : I/O improvements

scikit-ued's diffread function now supports Gatan's closed source DM3 and DM4 image formats.

Note that scikit-ued is also available on the conda-forge channel.

Release 1.0.0.0

This is the first stable release. Most changes from 0.5.9 are internal.

Public changes from 0.5.9 :

• available_dt_filters and available_first_stage_filters have been added to list available baseline-removal filters.

Further tweaks and bug fixes

A few new additions in this release:

• Added chemical_composition property to AtomicStructures
• Better string representations for Crystals and Lattices
• Added the skued.reflection function
• Fixed Lorentz factor calculations

0.4.11 : bug fixes and reliability improvements
