Question Last Updated on: 6/12/2026

Charts created in version 1.5.0 can only be opened in version 1.5.0 and newer.

LXEdge Version 1.5.0

Released: June 12, 2026

Major Updates

• Implement updated feature extraction for OSS-3 scoring.
• Allow review of chart “As Recorded” or as dressed up by “Examiner” or “Reviewer”. User can toggle among the various profiles.
• Significant changes to settings. Most notably, the “Chart” settings tab has been reorganized into “Chart Recording” and “Chart Appearance” tabs.
• Significant behind-the-scenes improvements related to settings.

Minor Updates

• Changes related to windows used to record or review video associated with chart:
  • Make smaller by default, with ability to resize
  • Always keep in front
• Allow window used to review media outside a chart to be resized
• Make thinner the lines used to indicate response and beginning and end of response onset window.
• Added white as an option to primary color picker.
• Remove the “More” button from the color picker.
• Add “Custom” question set type that should be used when none of the available question set types are appropriate. Replace “None” question set type with indication that user should select a valid question set type.
• Refine the appearance of the question label that appears inside chart by removing the box and increasing the range of the Question Label Font Size setting.
• Move setting to shrink chart to fit on a single page when printing to the System settings tab. Removed the Print setting tab.
• Added the ability to modify hotkeys related to running a chart to the Chart Recording tab.
• Modify implementation of “Very Low” audio setting so that post-conversion is no longer needed. This allows the LXEdge installer and footprint to be significantly smaller.
• Allow import of some older NCCA export files with non-numeric exam or chart numbers.
• Modify so simulator only creates data when needed behind the scenes. Slightly improves software performance.

Bug Fixes

• Navigating away from a chart while a note with unsaved changes was open would cause all sensor data to be lost for the chart.
• Charts would fail to load when .lxw file is corrupted in a certain way (missing File Reference).
• Two cameras of the same make and model could not be used at the same time.
• Import would fail for NCCA files with extremely low data rates.
• Software would crash when attempting to NCCA export a chart that had been created using NCCA import.
• Traces would not appear in imported charts for completely flatlined data in NCCA files.
• Charts with rare unusual traces would cause OSS-3 scoring to fail.
• Response Onset Window line widths would change with zoom level.
• Data rate was incorrect in NCCA export of charts created using Simulator.
• NCCA import would fail for files with unexpected label for Sample Rate.
• Memory usage by LXEdge would increase substantially over time while running and/or reviewing charts; this usage has been reduced significantly. Issues associated with the high memory usage included:
  • Short segments of dropped data in charts
  • Decreasingly responsive software performance, to the point the software was unusable
• LXEdge would crash when attempting to open a report that contains merge fields not found in the associated Personal History or Series information.
• In rare cases, failure of audio/video recording would result in empty recording files, even though recordings appeared to be working as expected.
• In rare cases, PF could be corrupted when a recording split occurred while recording audio in “Very Low” mode.
