Poisson Threshold Changes

Changes to default and available Poisson options have been made, following the recommendations in Isabel Abad-Alvaro, Eduardo Bolea, Francisco Laborda, Towards the harmonization of raw data processing in single particle inductively coupled plasma mass spectrometry, Talanta, Volume 305, 2026, 129575, ISSN 0039-9140.

• Default alpha is 1e-6
• MARLAP formulas are removed, Currie is the only recommended option for Poisson thresholding of single particle data.
• The correction factor ε, and η are now fixed at 1.

What's Changed

• Changes to the default Poisson limit options by @djdt in #45
• Perkin Elmer csv fix by @djdt in #48

Full Changelog: v2.0.5...v2.0.6

Release v2.0.5

• Batch image exports of histograms
• Correct restore of isotope options from session (density, response, ...)
• Size hint for Value Widget (should fix zero size on MacOS)

What's Changed

• Fix isotope options on session restore by @djdt in #46
• Image export for batch by @djdt in #47

Full Changelog: v2.0.4...v2.0.5

Release v2.0.4

• Fixes to number concs. by @djdt in #44

Full Changelog: v2.0.3...v2.0.4

Release v2.0.3

Spcal 2.0

A complete remake of SPCal to enable opening of multiple files concurrently and per-mass compound Poisson thresholding. The following features have been added.

• Redesign of the GUI into a series of docks
• Multiple files can be opened simultaneously
• TOF isotopes can be selected without needing to re-import files
• TOF results are shown in table
• Calculation of per-mass SIA from ionic data
• Peak mass spectra viewer
• Scatter plots for arbitrary peak data (i.e., ratios, sizes, sums)
• Improved multi-threading
• Improved batch processor (no longer need to load an example file).
• Improved ionic response calculator

Some changes have been made that require changes to current processing routines.

• The reference and sample tab are removed, transport efficiencies are now calculated via a calculator
• Old sessions will not be compatible with the new version.
• The exported result format has changed slightly
• Sessions no longer store all data, only a reference to the file path
• The default Poisson method is now the Currie method
• The lognormal-approximation and simulation methods for compound Poisson have been removed.

Known missing features

• Image exports of views are not yet implemented
• Image exports using the batch processors are not yet implemented
