LXEdge 1.2.7.11

Released: July 30, 2025

Minor Updates

• Allow recorded audio/video to be reviewed without needing to close and reopen the PF
• Use the global, instead of PF, setting for "Default Scorer". This allows someone reviewing PF on a different system to default to "Reviewer".
• Added ability to delete series if it does not contain charts
• Removed the "Delete", "Archive", and "E-mail" options from the 3-dots menu inside a PF
• Modifications related to Centering
  • Show smaller arrows that indicate the direction of the centering for charts created starting with this version. Charts created in earlier versions will now show a single line with arrows on both ends.
  • Significantly reduce the averaging time in the centering calculation
• Reimplemented the "Center All" button. Added setting that allows this to be shown or hidden
• For Paragon and Paragon X DAS, reduce the displayed trace amplitude by factor of 6 for the PGauge and Aux1 sensors.
• Updated many behind-the-scenes packages

Bug Fixes

• Chart would sometimes briefly pause when offsetting or responding to a question. This could lead to dropped data around this time.
• Indication of which subtab was selected had stopped appearing on the Templates and Settings views
• When running a chart, long question set names would cause scrolling to be needed to see all the question boxes
• Changes to Personal History and Series template could be lost following specific steps
• Chart would fail to open if it was created with two DAS units selected but at least one of them was disconnected
• Unexpected Series folders would appear in the Templates folder inside the user's LXEdge Directory
• Related to conversion from 1.1 to 1.2
  • Conversion would fail for PF that does not contain charts
  • Conversion would fail when double-clicking on .lxw file inside PF that requires conversion. Fix is to stop creating a backup of the PF before conversion.
• Related to NCCA Export and Import
  • NCCA export files for charts that had been converted from version 1.1 to 1.2 could have unusual sample rates
  • Properly handle missing data points in export and import
  • Slight timing differences from the original could occur when importing from an NCCA export file for the chart

LXEdge 1.2.6.7

Released: July 3, 2025

Bug Fixes

• In very rare cases, a section of non-critical chart data would be corrupted. This would cause a chart to fail to load. This was observed a single time, and the chart was able to be manually repaired. The bug allowing this has been fixed.
• Under rare circumstances, LXEdge would crash when attempting to select question list for a chart.
• Under rare circumstances, LXEdge would crash with error log indicating ESS could not be loaded.
• When importing from an NCCA export file, the EDA automatic trace was incorrectly being refiltered.
• When creating a new PF, it was possible to accidentally create and then navigate to a second new PF.

Bug Fixes

• Icons would sometimes be missing for the “Notes”, “Recorded Chart info”, and “Sensor” buttons in upper right corner of chart.
• Resolve some issues with combined charts; removed tools from combined charts.
• When copying the entire templates folder to a different location, some PF templates could not be used because the software was looking for sub-templates (e.g. Personal History) in the previous location.
• Audio/Video recording would be stopped when navigating to templates tab while inside PF. Resolved by preventing navigation to templates tab while in PF.
• When trying to start a chart while Personal History was incomplete, the Personal History would be opened but related item in navigation would not be selected.
• When a series contained both Acquaintance and non-Acquaintance charts, some scoring-related actions might not be able to be performed as expected.
• Clicking on the slider for adjusting gain would move the value to either the minimum (0.1) or maximum (0.99) value.
• On smaller screens, calipers information could be displayed too high to be visible.
• An extra number appeared after the question set names in a PF template.
• Deleting an unrun chart within a PF could lead to “Chart could not be found” errors or unexpected chart numbering.
• When editing a PF template, using button to close question set would not prevent the chart from being added to the template.
• Under certain conditions, charts would open to zoom other than 100%.
• Crash could occur when attempting to do actions like copy or archive multiple times.
• Crash would occur when ending chart and clicking on “OK” after already having ended the chart.
• In certain cases, NCCA export could cause crash or create files with unexpected missing datapoints.
• EDA data in NCCA export was not correct. This led to incorrect data when importing from NCCA export files.Test of Proportions could generate incorrect results because of incorrect determination of number of artifacts and/or numbers of relevant and comparison questions.

---

 

LXEdge 1.2.2.24

Released: May 29, 2025

Minor Updates

• Added heart and respiration rates to caliper statistics.
• Improve handling when device is disconnected while previewing chart. Users can no longer start a chart without sensor data present.

Bug Fixes

• Chart data could be lost in rare instances on certain machines due to failure of sensor data to merge at conclusion of running the chart. Resolved by:
  • Fixing some potential underlying causes
  • Keeping the .bin file containing the gridded data, even after merge should be complete
  • Checking for and resolving previous .bin file merge error when loading chart
• Artifacts could appear (rare, but frequency dependent on PC performance) in all sensors simultaneously. Resolved by using timing based on packet number from DAS when reviewing charts.
• If a question set was found to be missing while navigating to a chart, all charts for that series were reset. This could lead to inability to review completed charts.
• A series in a PF template containing two or more different question sets would not work as expected when running a PF using this template.
• Clicking on the gain slider would move the value to either the minimum (0.1) or maximum (99.9) value.

Minor Updates

• In Scoresheet “Scoring Result” dropdown, changed “Reactions” to “Response”.
• Added “Scoring Result” and “Countermeasures” to the Scoresheet PDF printout.
• Disabled adding notes during question onset. Adding notes at this time could prevent Onset button from being re-enabled or cause the Onset shading for the question to persist through the duration of the chart while running.
• Enable stripping by default when adding new fields to Personal History or Series templates.

Bug Fixes

• When quickly navigating in PF, last change to Personal History or Series information could be lost. Would sometimes lead to unexpected messages related to incomplete Personal History when starting chart.

• Issues when language set to Spanish
  • Examinee names did not appear in the PF grid on Home Page
  • NCCA import failed
• In rare cases, archiving a PF that had been converted from 1.1 to 1.2 would cause LXEdge to shut down without warning.
• In rare cases, when combining charts created in earlier versions of LXEdge some sensor data from one chart would push back the data from the next chart.
• Running a chart without traces appearing would cause a crash and subsequent inability to load this chart.
• PF conversion would fail for a PF containing a completely empty chart.
