Release Candidate 1.4.1rc2 (27. February 2025)

Release Highlights:

  • Introduces support for the OME-Zarr file format
  • Added Trainable Domain Adaptation Workflow
  • Native build for Apple Silicon (M1, M2, M3, M4) and Intel Macs
  • Tiff reading improvements
  • Added spherical texture object features, contributed by Oane Gros (publication)
  • Better user interface in dark mode

Notes:

  • Commercial solver support with gurobi 12.0.* for tracking with learning.
  • Native builds for Apple Silicon (M1, M2, M3, M4) and Intel Macs are available, which means better performance on these machines overall. Notes for the silicon version:
    • Currently only 2D networks are supported in the Neural Network and Trainable Domain Adaptation Workflows. These, however, run accelerated leveraging Metal Performance Shaders (mps).

Previous stable versions

macOS Big Sur and Monterey users please download ilastik 1.4.0 or newer

Dear macOS users, you are running macOS 11 (Big Sur), or newer please download the latest ilastik version (1.4.0 or newer). Older versions don't run anymore on OSX.

Version 1.4.0.post1 (10. November 2023)

Release Highlights:

  • Neural Network Workflow: run pre-trained neural networks from Bioimage.io Model Zoo in ilastik
    • Networks can run on CPU, GPU (choose the GPU build for Windows, or Linux), or on a remote server
    • No Neural Network training, yet - we’re working on it.
  • New startup screen!
  • Major UI and performance improvements for the Multicut Workflow
  • Stability/Usability improvements in the Carving Workflow
  • By popular demand: redo/undo for brush-strokes
  • Many bugfixes throughout

ilastik 1.4.0 is distributed in two versions for Windows and Linux. In addition to our regular build, you can download GPU-enabled builds. With these you can run pre-trained neural network models from the bioimage.io Model Zoo faster, if you have a compatible nvidia GPU on your system. All other workflows, besides the Neural Network Workflow (local) will work on the CPU, like before.
If you are interested in running the ilastik Neural Network Workflow on a remote GPU, e.g. if you have a powerful server in your facility, you have to check for additional installation instructions for the server part in the tiktorch repository. After you install the server part, you can use your regular ilastik installation as a client with the Neural Network Workflow (remote), ilastik will take care of the communication with the server.
Commercial solver support with gurobi 951 for tracking with learning. Note that on OSX there is no 3D preview in Carving, all other functionality should work as expected. We recommend OSX users to download the current beta version. If you have an Apple Silicon (M1/M2/M3), then please select the "Apple Silicon (arm64)" build.

Version 1.3.3

Includes various improvements and bug fixes.
A few highlights:
  • 1.3.3post3, projects are opened readonly in headless mode per default
  • Support for n5 volumes (https://github.com/saalfeldlab/n5)
  • Support for masks in Pixel Classification (an additional dataset can be supplied that disables computation of probabilities wherever it is 0 -> speeds up computation in cases with a lot of background
  • Atlas Mask overlays for Object classification (an additional dataset can be supplied. Pixel values of this additional mask are included in result tables but not used in classification.)
  • counting fixes (saving boxes, import/export of boxes, interaction improvements)
  • autocontext now takes arbitrary data types (was previously limited to uint8), but mind the memory footprint! We still recommend to use uint8.
  • carving improvements, more efficient memory utilization
  • applet bar improvement, redesign
  • a lot of internal backend cleanups/improvements
  • a lot of internal GUI cleanups/improvements
  • updated dependency stack
For more details, see the Release Notes. Commercial solver support for cplex version 1290 and gurobi 811 for tracking with learning.
