2. Your task has compile time optimizations on: Hardware Settings -> Code Generation -> Compiler optimization level = Optimizations on (faster runs))
We are also taking this opportunity to fix a bug for NHP users of NI card 6071e and 6713. See the release notes for Dexterit-E for a full list of changes with 3.9.4.
*Update* Dexterit-E and Dexterit-E Explorer 3.9.3 released.
Dexterit-E & Dexterit-E Explorer 3.9.3 contains important bug fixes and usability enhancements. . This is considered a mandatory update.
NOTE: A bug in the exporting of analysis results for Trails A+B was found, which has been present since Dexterit-E 3.7. Any studies using Trails A+B should re-analyze their data. This bug does not affect studies that used Trails A alone, or Trails B alone.
Details of the bug: When outputting Trail Making analysis results to CSV, Dexterit-E incorrectly treated Trails A+B as if there were only Trails B data. While fixing this bug, a new feature was added to improve clarity on what is being output: there are now 3 explicit options: Trail Making A, Trail Making B, Trail Making A+B. This change has been implemented in both Dexterit-E and Dexterit-E Explorer.

Summary of release notes for Dexterit-E 3.9.2 (Oct 2021)
Dexterit-E 3.9.2 contains important stability fixes for rare error conditions. This is considered a mandatory update.
Dexterit-E 3.9.1 contains bug fixes and usability enhancements.
Dexterit-E 3.9.1 contains a critical bug fix for users of the Kinarm Gaze Tracker. There was a problem in Dexterit-E 3.9.0 where gaze events (e.g., blink start, blink end, etc.) were always stored at time zero. For Kinarm Gaze Tracker users this is considered a necessary update.
NOTE: Some continuous time Simulink blocks (as opposed to discrete time blocks) can cause CPU overload conditions when using Dexterit-E 3.9 even though the same task may have worked in Dexterit-E 3.8 or earlier. All continuous time blocks can be replaced using a discrete equivalent. If you have a task where this problem happens, contact Kinarm support for assistance.
NOTE: The Custom Task Programming Guide for Dexterit-E 3.9 states erroneously that exam files can be up to 4 GB in length. Exam files can actually be up to 2 GB in length. For a KINARM Exoskeleton collecting 16 channels of analog data (40 channels of data total) this equates to a single exam of 15-20 hours. The duration will vary depending on the number of channels of data collected, complexity of the subject display and the compression of the data.

- Dexterit-E™ 3.9.0; and
- Dexterit-E Explorer™ 3.9.0
- New Kinarm Standard Tests
- Arm Movement Matching – the purpose of this test is to assess the ability of a subject to perceive motion of their arm in the horizontal workspace.
- Arm Posture Perturbation – the purpose of this test is to assess the ability of a subject to respond to unexpected disturbances of the arm when maintaining their hand at a spatial goal. (Exo only.)
- MATLAB 2019b support
- Input files for Task Programs – it is now possible to pass a user-generated file from the Dexterit-E Computer to the Robot Computer which can then be used in your Task Program. (This feature requires a Robot Computer with PN 13107 or higher.)
- See the release notes for Dexterit-E and Dexterit-E Explorer for a full list of new features.
When you upgrade to Dexterit-E 3.9, you will need to:
- upgrade to Dexterit-E Explorer 3.9.0 at the same time.
- Dexterit-E 3.9 uses a new file format to save exam data that is not backward compatible with previous (1.5 and earlier) releases of Dexterit-E Explorer.
- obtain the latest release of the Kinarm Analysis Scripts in order to load data recorded with Dexterit-E 3.9 or later. The updated MATLAB scripts are backwards compatible with previous releases and include several enhancements for usability and performance.
- contact support@kinarm.com to obtain a new license key for Dexterit-E 3.9.
- As always, Dexterit-E Explorer does not require a license and can be run on any Windows 64 bit or Mac OSx computer.
