    • xml format for contraint-files (incl. schema validation)
    • more flexible constraint definitions, masking of single matrix elements
    • error correction enabled for tertiary and merged channel
    • HMM - choice between "smooting model" (r-replacement) and "Baum-Welch algorithm"
  • Eventselection
    • release TC3 and unsupervised eventselection 
    • separate section for tracking and event selection
    • new option "event channel"
  • Minor GUI improvements, obsolete options removed, ...
  • Browser
    • option "show by classification" added, to show color code of a predefined classifier
    • zoom/pan feature for image view panel 
    • time slider updates less often
  • Documentation updated
  • Cluster service moved to a separate repository
  • Bug fixes and code cleanup 

1.4.1 (2013/10/16)

  • fixed battery package 
  • bug fixes 

1.4.0 (2013/04/18)

  • added merged channel classifier for feature concatenation of other channels
  • plugin system for segmentation 
  • various bug fixes
  • cluster setup simplified

1.2.5 (2012/01/03)

1.2.4 (2011/09/07)

1.2.3 (2011/08/23)

  • fixed an issue running on MacOS 10.5
  • fixed several GUI bugs and improved usability
  • fixed multi-plate support for error correction and enabled error correction features in the GUI

1.2.2 (2011/04/15)

  • added support for temporal units (minutes, seconds) for the tracking module in case time-stamp meta-data is available
  • added the structure path to the path mapping (for cluster execution)
  • change the image path for already scanned structures loaded from pickle files (bug fix)

1.2.1 (2011-04-12)

  • changed image import strategy: file info and meta data are loaded only for one plate at a time to reduce memory consumption, changed structure file to Python pickle again
  • added progress dialog when plates are changed (higher delay due to dynamic loading)
  • fixed overwrite of rendering channels with same name (problem between physical and logical channels)
  • browser is reseted after loading of settings and import of image data
  • added more warnings and consistency checks for image import
  • added optional reformatting of well names (set subwell to 2-digit integer)

1.2.0 (2011/04/05)

  • fixed severe crash caused by PyQt4
  • browser opens on data import automatically
  • added support for multiple plates (including annotation, processing, cluster execution)
  • fixed index problem on loading annotations
  • fixed channel selection problem

1.1.2 (2011/01/28)

  • fixed bug writing CellCounter XML files (time information is based on frame indices again)
  • fixed bugs in learning SVM classifier
  • added "Show Object Contours" shortcut to the browser
  • improved speed for 32bit Windows (VC9 whole program optimization)

1.1.1 (2011/01/24)

  • enhanced the browser (look-up tables, faster rendering, support for multiple channels and object regions)
  • fixed a bug in setting primary features
  • fixed a bug in feature normalization (regularization for constant features) 
  • changed SVM training to list-use (no zero-insert required)

1.1.0 (2011-01-04)

  • redesign of input image scan (save structure file as compressed text in input path)
  • added support for gallery images of events (sequence of object images per event and branch)
  • added support for full feature export of events
  • reactivated cluster support, added "batch size" for experiments with very high number of positions (and no time-lapse)
