Summary of changes in arivis Vision4D 4.0, released 30 September 2022.

New & Noteworthy:

  • New Automatic Neuron Tracing Module: automatic detection, interactive editing, visualization and features of traces in neuron imaging
  • Much cleaner and simplified Object Style UI
  • Import Perkin Elmer Operetta and Columbus datasets

Automatic Tracing workflow, optimized for neurons:

  • New: introducing a new object type "Trace"
  • New: show traces as cones or skeleton in 2D and 3D
  • New: automatic tracing analysis operations with two powerful algorithms
  • New: neuron tracing starting with a segment as cell body (or without)
  • New: manual trace editing with the Trace Tool
  • New: ability to manually split, merge, refine, or simplify trace sections within the Trace Tool
  • New: interactive Draw mode to add missing sections or start from scratch (or start from a segment as cell body)
  • New: action to split trace components (neurites, cell body) apart

Analysis:

  • New: Tracking operation now saves the center calculation method used
  • New: tracks are correctly retained even if their segments have been deleted
  • New: track features are computed based on the stored center calculation
  • New: Distances operation calculates statistics for the closest n objects
  • New: Background Correction operation supports different methods now (including morphology)
  • New: Analysis operations now create object styles to color results
  • New: operation categories "Use segments" and "Use track & groups" are now combined as "Use objects"
  • improved: region growing results contain the complete geometry of seeds now
  • improved: performance improvements for feature calculations for tracks and tracked objects
  • improved: better support for scaled analysis of very large planes
  • improved: handling of large ML trainings
  • improved: allow to choose target directory for extracting zpipeline packages
  • improved: do not show sample pipelines that use operations not covered by the current license
  • fix: missing configure output menu entry

Object Styles:

  • New: simplified style rule UI
  • New: each tag has a single style rule now
  • New: ability to change the order of processing the style definitions by drag & drop
  • New: simplified minimum set of style properties
  • New: create styles with specific style properties for object types tracks and traces
  • improved: 2D and 3D style settings have been combined for ease of use
  • improved: proper Apply button to save the settings but keep the styles dialog open

Data & Import:

  • New: media handler for reading Perkin Elmer Operetta and Columbus datasets
  • New: wellplate import scenario
  • New: the offset of an image set is displayed more prominently in the Info Viewer
  • New: ability to delete all objects of several image sets
  • improved: import the names of the channels of an OME TIFF
  • improved: export OME TIFF with a newer OME schema (June 2016, version 2)
  • fix: sort order for the well field in the Navigator panel

Scripting:

  • new: scripting support for the new trace objects
  • new: scripting support for the 4D Viewer Storyboard
  • improved: 4D Viewer scripting capabilities

General:

  • New: remember movie export settings
  • New: allow to open the License Tool directly in case the maintenance has expired
  • improved: visibility of the reason for a deactivated license (e.g. cloned)
  • improved: updated included Sentinel driver to version 8.4
  • various bug fixes and stability improvements
