D47crunch v2.4.1

New feature

• D4x.plot_single_session() is now able to return the data to be plotted instead of plotting directly (used by D4Xgui, contributed by Miguel Bernecker).

Bugfix

• Simpler (better?) computation of D4x repeatability at the session level when using pooled regression method.

D47crunch v2.4.0

New feature

• Support for Δ₄₉ standardization (#15).

D47crunch v2.3.2

Bug fix

• Add rich dependency

D47crunch v2.3.1

Released on 2023-07-22

Improvements

• Better help text and examples for CLI

D47crunch v2.3.0

Released on 2023-07-21

New feature

• New method D4xdata.save_D4x_correl() to export a list of Δ_4x values along with their SE and correlation matrix.

Other changes

• The CLI now also calls save_D4x_correl().

D47crunch v2.2.1

Released on 2023-07-20

New feature

• The CLI now processes Δ48 as well as Δ47 data, thanks to the --D48 option.

D47crunch v2.2.0

Released on 2023-07-20

Command-line interface (CLI)

• Rejoice, you no longer need to know Python: it is now possible to process a multi-session Δ47 dataset with custom anchors and custom UID/sample exclusion list by simply calling D47crunch -a anchors.csv -e exclude.csv -o outdir rawdata.csv.

New features

• Add yspan option to D4xdata.plot_residuals()
• Added shuffle option to virtual_data().
• Added filetype option to D4xdata.plot_sessions().
• Added dpi option to D4xdata.plot_sessions(), D4xdata.plot_residuals().

Bugfix

• Fix error in D4xdata.plot_residuals() when hist = False and kde = False.

D47crunch v2.1.1

Released on 2023-05-16

Bugfix

• D4xdata.compute_r() uses an improved computation for degrees of freedom for arbitrary subsets of sessions and/or samples, yielding more estimates of analytical repeatabilities for Δ47 and Δ48.

New feature

• Added kde option to D4xdata.plot_residuals()

Other changes

• Minor improvement to y axis tick labels) in D4xdata.plot_residuals().

D47crunch v2.1.0

Released on 2023-05-14

New feature

• D4xdata.plot_bulk_compositions() plots the dispersion of δ13C and δ18O values for each sample.

D47crunch v2.0.6

Released on 2023-05-13

Bugfix

• Eliminate some spurious debugging messages in _fullcovar()
