what's new?

This page summarizes the broad user-visible changes in the current and earlier EMEGS (Qt version) releases.

Currently in development

Version

• Modernized cross-platform Qt 6 application, help system, and portable deployment.
• Resumable ERP/ERF batch processing with configurable ICA ocular correction, component review, and statistical artefact review.
• Improved workspaces, recovery, navigation, plotting, and multi-dataset visualization.
• Extended ECG editing and SPECTRAL analysis with more reproducible processing and export.

Workspaces and ERP/ERF: updated English guide

• Workspace settings and recovery: understand live settings, saved workspaces, study defaults and recovery snapshots.
• Batch construction: relative-path filters, SCADS/EWH5 condition searches and subject-matched batches.
• ERP/ERF preprocessing: continuous ICA correction, named processing ranges and independent interaction/reuse controls.
• Branches and subject overrides: preserve established results while testing downstream alternatives or supported subject-specific settings.
• Grouping and exact trial selection, with branch/profile-aware outcome reports and previewed cleanup.

The broader English Help refresh is ongoing. Older screenshots and untranslated editions may still show previous controls. ERP/ERF and wavelet t-tests, including permutation t-tests, remain under development and are not presented here as fully validated workflows.

Version 2.0

• 64-bit Linux and macOS packages, including an Ubuntu installation package.
• German user-interface support and initial French, Italian, and Spanish translations.
• Expanded ECG, EDA, STARTLE, MARKER, and database-result analysis.
• Colour-coded EEG artefact detection and timing/database editing.

Version 1.9

• Added complete ERP analysis for BDF recordings.

Version 1.8

• Introduced the text-based .qecfg sensor-configuration format.
• Added regression and aligned-artefact-average ocular correction for ERP data.
• Replaced the earlier R integration with an Rserve client.

Version 1.7

• Added planar ERP/ERF maps and the native 3D viewer.
• Added study folders, initial SQL result storage, ECG analysis, and R-based statistics.
• Added application preferences, MARKER analysis, and the first Linux RPM package.

Version 1.6

• Introduced the multi-analysis framework for ECG, EDA, ERP, and related workflows.
• Moved signal processing into the platform-independent emegsLib library.
• Added QGraphicsView-based displays for smaller channel sets.

Version 1.5

• Added interactive planar sensor-layout adjustment and sensor-group tools.
• Restored intervals and sensor configurations from saved workspaces.
• Added Neuroscan CNT display support.

Version 1.4

• Added BDF preprocessing, epoch extraction, SCADS processing, and averaging.
• Added serial epoch display and BDT/TAW display support.
• Added adjustable and exportable sensor configurations.
