What's new in Huygens 23.04

Huygens Professional, Essential, Localizer & Core

  • (All) Change in scripting with images/tables:
    • Creating images or tables returns a handle instead of their name.
      • Handles are to be used for Tcl and Python scripting.
      • Previously, the image name served this purpose and images could therefore not be renamed.
    • Rename images or tables without creating copies
      • Right-click the thumbnail and select "Rename Image/Table" or press F2 as a shortcut.
      • Use Tcl scripting with the rename command 'oldName rename newName'
  • (P/L) Python Scripting:
    • Updated Python from version 3.7.8 to version 3.11.1
    • Updated the Python image class to be compatible with image handles and image names.
  • (E/P) Deconvolution Express:
    • Improved automatic SNR and Acuity estimation. The suggested Acuity can no longer be out of the normal range.
  • (E/P/C) Deconvolution algorithms:
    • (CMLE/GMLE) Added a correction to the regularization for images with only one or two z slices.
    • (CMLE) Improved the correction to the regularization for under and oversampled images. This change is almost disabled when acuity is disabled, for better backwards compatibility.
    • Note: Deconvolution templates for shallow and/or very under or oversampled images might need adjustment.
  • (E/P) Workflow Processor:
    • Added an "Analyze Objects" task for doing object analysis in batch (see below).
    • Added "Automatic" deconvolution algorithm, which does deconvolution with automatically found settings like in the Decon Express.
    • Added the option to do Crosstalk Correction by using a Crosstalk Correction Template.
  • (E/P/C) Batch Object Analysis
    • It is now possible to do Object Analysis in batch by using a new task in the Workflow Processor.
    • (E/P) The Workflow Designer in the Object Analyzer has been improved and modified to support batch processing.
      • The "Time frame and detector" task has been reworked to a "Time series" task. It is now possible to apply parts of a workflow to each time frame in an image. This replaces some old task specific options like "Analyze time series". Support for analyzing raw array detector images has been deprecated.
      • The "Set visualization task" has been deprecated.
      • In the "Basic ROI operations" and "Set anchor" tasks it is now possible to set the segmentation group for some options.
      • The "Advanced ROI operations" task has been expanded with more options.
      • A new "ROI intensity removal" task has been added which can be used to remove intensity from an image by using the ROI.
  • (E/P/L) The Object Analyzer
    • Added a tutorial.
    • (E/P) Reported parameters:
      • It is now possible to save and load custom selections of parameters using templates.
    • Added the "HighContrast" parameters to the list of coloring parameters in the visualization tab. This parameter can be used to color objects in such a way nearby objects have contrasting colors.
    • Added mouse modes for drawing selections in regular shapes.
    • Analysis of 2D XY slices will no longer report parameters that are irrelevant or misleading for 2 dimensional images.
    • Added/improved GPU support for merging and removing objects, selecting objects with the lasso tool, and for various analysis operations.
    • Improve selection of objects. It is now possible to select multiple objects by using Ctrl + Left mouse button when in the analyze mouse mode. Selected objects will also be highlighted more clearly.
  • (E/P) Crosstalk Corrector:
    • Added support to crosstalk corrector for unprocessed Array Detector images
    • Added Crosstalk Correction Templates.
    • Updated the Mip preview.
  • (All) File readers:
    • HDF5 reader:
      • Read Luxendo metadata.
      • Added support for HDF5 images split over multiple files.
  • (C) Huygens command line interface (CLI):
    • Start Huygens Core from a command line with paths to a workflow template and an image to apply that workflow template to that image.
      • With this it becomes easy to integrate Huygens deconvolution and processing in your custom workflows.
      • This makes it easy to implement Huygens with a job scheduler (e.g. Slurm).

Minor Changes

    • Added detector cropping option to the Cropper.
    • Gallery tool can visualize slices across the detector images.

    • Ome-Tiff reader:

    • New coloring options: it is now possible to color the clusters based on some of their properties. For instance clusters with the same parent can be given the same color.
    • Add the "HighContrast" parameters to the list of coloring parameters in the visualization tab. This parameter can be used to color objects in such a way nearby clusters have contrasting colors.
