A persistent prerelease where build artifacts for the current tip will be deposited

v0.8.15

For windows, download Refl1D-0.8.15-self-extracting.exe and run it to extract the archive. Go to the extracted directory and click on refl1d_gui.bat. This will open a dialog saying that the application is untrusted with a "Don't run" button at the bottom. Click on "more info" and a "Run anyway" button will appear.

Use pip install refl1d wxpython to install Refl1D in your python environment.

For OSX on an M1/M2 processor, you must install wxpython from conda.

1. conda create -n refl1d
2. conda activate refl1d
3. conda install python=3.9
4. conda install wxpython numba
5. pip install bumps refl1d
   Then you can start the refl1d GUI from the command line with pythonw -m refl1d.main --edit

2021-11-18 v0.8.15

• preliminary support for theta_offset in PolarizedNeutronProbe
• preserve manual zoom view on R during fits
• fix wx and matplotlib bug (setTitle)
• use numba JIT for reflectometry kernel, convolve, etc (replacing all uses of C/C++ extensions)
• (this results in a pure Python wheel)
• use magnetic_smooth_profile in "record_point", same as is done for non-magnetic profiles
• FunctionalLayer can now accept lists of parameters
• oversampling helper added (currently called refl1d.oversampling)
• much faster "Model Uncertainty" view calculation for large profiles
• update to bumps 0.8.1

v0.8.14

For windows, download Refl1D-0.8.14-exe.zip and extract the archive. Go to the extracted directory and click on refl1d_gui.bat. This will open a dialog saying that the application is untrusted with a "Don't run" button at the bottom. Click on "more info" and a "Run anyway" button will appear.

2021-02-09 v0.8.14

• numba included in windows zipped executable
• use numba rather than C++ for fast polymer calculations
• wheels now built with stable ABI (one wheel per platform for all Python > 3.2)
• drop py27 support for compiled modules
• tolerance adjusted on polymer_test to account for sensitivity to input parameters
• display of chisq in plot window works again
• fix selection mask for load4 to work on theta and lambda as well as Q and R
• use github actions to build wheels and deploy

2020-10-23 v0.8.12

• support uniform resolution in addition to gaussian resolution
• implement oversample() and critical_edge() for QProbe
• support variable wavelength probes for materials mixtures
• add irho to the profile contour plots
• save magnetic twist contour in output directory; it is not yet plotted
• simplify realignment usage to 'refl1d align ...'
• improve support for complex amplitude (beam corrections, interpolation)
• restore DREAM fitter efficiency (it should now require fewer burn-in steps)
• restore parallel processing for GUI
• reenable python 2.7 support

See CHANGES.rst for complete history.

v0.8.11

Documentation: http://refl1d.readthedocs.org

2020-06-11 v0.8.11

• support list values for angle and wavelength in column data format
• use dQ from datafile rather than calculating it from dL and dT
• adjust dQ with sample broadening rather than calculating it from dL and dT
• fix json output so saving the fit doesn't raise an error
• fix functional magnetic profile so [rho, rho] is not treated as rho, theta.
• fix plots to show magnetic angle when not the standard magnetic angle
• fix legends when show magnetic angles on plots
• wxpython is now an optional dependency
• bumps: support limits=(min, max) for pm and pmp parameter ranges
• bumps: fix --entropy command line option
• bumps: parallel fitting suppressed in GUI for now---need to reuse thread pool

BREAKING CHANGE: default thetaM for functional magnetism changed from 0 to 270

See CHANGES.rst for complete history.

v0.8.10

Documentation: http://refl1d.readthedocs.org
