Releases | Open Source Science

Fixes a crash in "show fit correlation" due to NULL pointer
Fixed broken optimization in stopping force calculation, results are not affected
Default fitting is slow mode only, dual (fast + slow) can be enabled
Added SIMNRA namespace to XML (IDF) export, layer roughness (gamma) is now included in exported IDF files so that SIMNRA can read it correctly
Some more internal help
Added "reset fit ranges" command
Improved the example
Code cleanup
Distribution improvements
Bugfixes

What's Changed

Added a command (show fit correlation) to output fit parameter correlation coefficients. This was previously only output after fitting if verbosity level was MSG_VERBOSE.
Calculation of confidence limits (results not to be trusted!)
Kinematics calculator kin can also calculate kinematics of R33 file based reactions
More warning messages if sample parsing fails

Interactive mode uses readline (enables editing) if available
Added support for IDF import and export of detector foil (stopping foil)
Reset current working directory in Qt UI always when running the script, not just when the file is first loaded.
Added reaction yield scaling (ad-hoc). Changed handling of add reaction modifiers (cs, min, max, yield) so that these can be applied also to R33 reactions using load reaction.
help version command reports JIBAL, GSL and libxml2 library version numbers too and runs libxml2 version check (results are not reported to UI if running qjabs)
Print valid options if ambiguous or invalid option is given when using set script command.
QJaBS: Logscale counts axis in UI starts from 0.1 counts.
GitHub build actions by @jaakkojulin in https://github.com/JYU-IBA/jabs/pull/18
Depth resolution is calculated in debug output (not in release version).
Miscellanous cleanup, refactoring and minor bug fixes

Bugfix: Fixed a bug where hitting the maximum number of bricks did not produce any output at all since "last brick" was not set. Added also a warning message and debug output if this happens.
Bugfix: Missing allocation in fit jspaces (Jacobian calculation) for Z specific detector calibrations caused crashes when detector specific calibrations were used and a fit was attempted
Bugfix: Polynomial calibration is saved correctly when using save calib. Changes uses of polynomial to poly, there was some mixed usage.
Bugfix: Reaction Q-value was printed in keV but with "MeV" as a unit.
Bugfix: Reference spectra can be loaded from a file starting with a number (bug in detector number detection)
Bugfix (?): RK4 could under certain circumstances (stopping step high compared to ion energy) evaluate stopping below GSTO data minimum
Bugfix: Reaction name is calculated properly when reactions are created by plugins.
Bugfix: Missing stopping data warning when reaction product is a neutron is now suppressed.
Bugfix: NULL des_table could have been referenced (if out of memory).
Bugfix: Fixed a crash due to NULL pointer dereferencing when running show reactions command with debug mode on.

IDF export by @jaakkojulin in https://github.com/JYU-IBA/jabs/pull/17
Some support for elliptical and square apertures for better compatibility with IDF
README updated

One more screening model, more verbose error messages related to screening tables
Plot can be saved as PDF (if it works) in QJaBS
Bugfix: too many quotation marks in CSV output headers
Bugfix: thin last layers were not always simulated. Added a test case for this.
Bugfix: even if a reaction product stopped in the detector foil, simulation did not
Bugfix: neutrons (Z=0) were broken
Bugfix: energy loss derivative calculation assumed too high derivatives, possibly leading to nasty looking spectra
Parameter tuning
Minor restructuring

Adds universal cross sections (slow) and scattering integral solver code
Cross sections can be pretabulated when simulation is initialized, helpful if cross sections are slow to evaluate
Handling of low energy cutoff changed again
Simulation is aborted if incident ion energy is too high compared to available stopping data
Cleanup
Several bugfixes, see list below

Fit workspace restructuring and OpenMP support by @jaakkojulin in https://github.com/JYU-IBA/jabs/pull/16
Energy calibration monotonicity checks
Tuning of low energy cutoff
Improved handling of JIBAL GSTO data, slight speedup and better warnings
Verbosity of messages can be changed, some output is suppressed with default verbosity
Slightly better compatibility with dark mode (macOS) by changing some colors and using default colors in other places

Layers can have density, thickness in nm can be output if density is given
Thickness distribution (roughness) can be loaded from a file
RBS minus sign solution can be calculated and is calculated by default.
Restructuring of fit function, bugfixes when NOT fitting fluence corrected
Beginnings of plugin support, cross section (or reaction) can be loaded using a dynamically loaded library. Not supported on Windows and support needs to be turned on at compile time, the default is no plugin support.
Support for transmission geometry
Feature to convert IDF files to JaBS scripts and import them. Only supports a small subset of IDF.
Improvements in output messages
Reduction of compiler warnings
Several memory leaks fixed

QCustomPlot updated to version 2.1.1, fixes some HIDPI related issues
Small UI improvements (zoom label, preferences dialog size)
Added one new (old) test
Added sanity checks and message when experimental spectrum is loaded
Added filename and line number to prompt when processing files (either loaded via "script load" or given as input). Interactive prompt stays the same. Full Changelog: https://github.com/JYU-IBA/jabs/compare/v0.6.5...v0.6.6
