First KNOSSOS Qt Release
KNOSSOS v4.0 - Change Log
KNOSSOS is a software tool for the visualization and annotation of 3D image data and was developed for the rapid reconstruction of neural morphology and connectivity.
General Information
Release Date: Date 03.06.2014
KNOSSOS 4.0 is a milestone release with a completely reworked graphical user interface based on
the QT framework.

Roadmap:
v4.1:
- Interactive Python scripting
- Volume annotation and visualization of large scale segmentation data
Known Bugs
UI Improvements
- Nicer look and feel
- Native file dialogs and ui elements
- Restructured menu:
- Icons and shortcut information in the menu bar
- Current workmodes are marked with a check
- A Toolbar with a collection of important widgets
- Restructured Viewport Settings Widget
- Tooltips
- Integrated documentation
- Unsaved changes are indicated with an (*) in the titlebar
Features
Tracing:
- Integration of client-server based task management (with a Python django backend), that allows annotators to efficiently submit
their tracings to a database. - Extensive filtering and listing of trees and nodes (with regular expression support) based on comments and other properties.
- Visual selection and operations on groups of nodes in all viewports.
- Show only selected trees.
Dataset:
- Real time arbitrary angle slicing for voxel data (use eg l or k for rotations).
- Datasets can now be streamed from remote server locations (http based, works well for connection speeds > 10 MBit/s with compression)
- Datasets can be compressed (each datacube individually) with JPG2000 or JPEG with real time decompression during the navigation (multi-threaded).
Typical values for 3D EM datasets without obvious compression artefacts are ~1 bit / voxel. Lossless compression is also supported. - On-the-fly dataset changes possible under File->Load Dataset, no more Python Launcher required.
- KNOSSOS remembers the last used dataset and loads it on launching.
Skeleton:
- Multiple skeletons can now be loaded at the same time (select more than one in the file dialog).
- Load Skeletons by drag'n dropping them into KNOSSOS.
Changes
- The Python Launcher has been removed.
- Moving Viewports around now works with Ctrl+AltLeft mouse drag
- The synchonization of multiple KNOSSOS instances is currently not supported any more
- The format for custom preferences is now saved in a key value file structure (.conf)
- Default Folder for Skeleton Files is now in the standard data location (i.e for Windows: %AppData%/MPIMF and for Linux: /home/user/.local/share/data/MPIMF)
- A Mac OS X Version (>= version 10.9) will be available soon.
- Debian Package for Linux (Tested on Ubuntu [i386/amd64](>= version 12))
