Released: 2026-03-19

New & Noteworthy

  • New data aggregation with heat map view for well plates directly in arivis Pro
  • Export aggregation settings to arivis Hub and get the same results as in arivis Pro at a larger scale
  • Preview feature: enable "Formula-based feature creation" to create new custom features using a mathematical formula

Multi Run & Aggregation (Batch license required)

  • new: Aggregate Features operation in Analysis Pipeline
  • new: pre-define statistical features as needed in the Aggregate Features operation (e.g. count, min, max, mean, ratio ...)
  • new: use Multi Run in the Analysis Panel to run the pipeline and aggregate object features for multiple wells or fields of a well plate document
  • new: Data Aggregation window to explore the aggregated values for the well plate
  • new: show distribution of an aggregated value as heat map for the well plate in Data Aggregation window
  • new: export pipelines with Aggregate Features settings to arivis Hub
  • new: export aggregated results as XLS or CSV
  • new: Multi Run adds a new tag "Multi Run" to allow filtering for the resulting objects of the same run easily
  • improved: current image type is preselected for Multi Run

Analysis

  • new: Formula-based custom feature allows to compute a feature based on a freely definable mathematical formula (Preview Feature)
  • new: use values from referenced objects in Formula-based features to create e.g. ratio to parent
  • new: 3D Feret Max object feature
  • new: Maximum Inscribed Circle/Sphere features for filled objects
  • improved: DL Reconstruction and DL segmenter remember model specifics in pipeline to recover custom settings in case the model is missing
  • improved: allow duplicate channels to be used for DL Reconstruction or DL segmenter
  • improved: several operations which export data (e.g as XLS or CSV) do better validation for the configures export name or path
  • improved: don't try to use CUDA if support ist not installed or GPU is missing or disabled
  • improved: determinism of Cellpose results on different machines/hardwares (please be aware: the results could slightly differ from 4.4 pipelines)
  • improved: performance of Cellpose and DL inference (especially if running on CPU)
  • improved: updated Matryoshka.python sample scrip
  • change: using ONNX Runtime 1.23 and CUDA 12.9 now
  • change: some demo data and the related sample pipelines have been updated
  • fix: sometimes Cellpose operation did not deliver the same results as in previous versions of arivis Pro
  • fix: some sample pipelines were using deprecated operations
  • fix: DL Trainer had some issues with unicode characters in dataset names

4D Viewer

  • improved: settings for export segments as surface use the same surface quality (and smoothing) as in the viewer
  • improved: storyboards for data with more than 8 channels
  • improved: show preview icon in viewer label while isosurface extraction dialog is open

2D Viewer

  • improved: selected objects are visualized with a yellow outline now in the 2D Viewer (similar to the 4D Viewer)
  • improved: object selection in 2D Viewer by left click + drag a rectangle is now updated live (Preview Feature)
  • improved: left click + drag to select objects in the 2D Viewer can be started from everywhere (even inside an object)

Import & Data Handling

  • improved: consider the PlateId for naming on import well plate datasets
  • fix: wrong tile positions for PE well plate data without orientation matrix specified in the metadata
  • fix: import problems for data from PE Acapella
  • fix: for some CZI files it was not possible to hide some channels
  • fix: set time does not work properly for some CZI files

General

  • new: a link to request a trial license is available right from the License Selection dialog
  • new: arivis Pro can be installed from the ZEISS Microscopy Installer (ZMI)
  • change: arivis Pro stand alone installer provides Docker Desktop version 4.56.0 now

System requirements

  • change: supported & tested platform is Windows 11
  • change: arivis Pro requires a GPU providing CUDA compute capabilities ≥ 7.5 for ML/DL acceleration 
  • change: NVIDIA GPU minimum driver version is 576.02 
  • change: arivis Pro stand-alone installer provides Docker Desktop version 4.56.0 
  • change: Docker based instance segmentation requires NVIDIA GPU with CUDA Compute Capability ≥ 7.0 now

Misc

  • improved: several updates & fixes for the help content
  • improved: updated version of the ZEISS Help Viewer
  • fix: potential crashes running in Windows 11 when operations on very large data sets run in parallel with many threads
  • various smaller bug fixes and improvements
