Application

  • Software license: EthoVision XT can now be purchased with a software license instead of a hardware key. Licenses can be configured as:
    • Fixed License: Tied to a single computer.
    • Floating License: Shared across multiple computers (one user at a time).

Video Technology

  • New digital camera drivers:
    • Basler cameras: updated to driver version 6.2 (from 5.1).
    • Daheng cameras: updated to driver version 1.12 (from 1.6).
  • Deep Learning GPU Compatibility: Expanded support for NVIDIA GPUs. Newly tested cards include:
    • NVIDIA Quadro P2000
    • NVIDIA Quadro P2200
    • NVIDIA T1200

Trial Control

  • Permutation for random variables: A Permutation option ensures that a value is not repeated until all other values have been used—useful for randomized trial designs.
  • Extended Subrule repeat interval: You can now set repeat intervals of up to 99 hours, 59 minutes, 59 seconds (previously limited to 24 hours).

Data Acquisition

  • Import trials from other experiments: Combine data from separate experiments into one dataset—for example, across multiple PhenoTyper cages or DanioVision units.
  • Show/hide body points in Manual Scoring: Nose and tail-base points can now be toggled on/off in the manual scoring screen for better event annotation.

Data Analysis & Visualization

  • Group charts: Box-and-whisker plots can now optionally display underlying data points (scatter dots).
  • Customizable tracks: Adjust track thickness and body point size in:
    • Detection Settings
    • Integrated Visualization
  • Improved results table: Headers now clearly indicate independent variables in the statistics output.

Documentation Updates

  • Temperature Control Unit (DanioVision): Now covered in the DanioVision DVOC-0041 Reference Manual.
  • Calcium Imaging: New chapter added for experiments combining EthoVision XT with Inscopix nVista/nVoke systems.
  • Fear Conditioning: Quick Start Guide for Ugo Basile systems now integrated into the Application Manual.
  • Access: Go to Start Menu > Apps > Noldus > EthoVision XT 17 Other Documentation.

Experiment Templates

  • Track3D: Two new experiment templates for 3D tracking:
    • Flight chamber
    • Water tank
