The ImageJ framework for semi-automated tracing of neurons and other tube-like structures. It is part of the Fiji distribution of ImageJ. For details, please see http://imagej.net/SNT
SNT is currently under heavy development. Because the ongoing work does not guaranty full backwards compatibility with previous versions, the latest pre-releases are not yet made available through Fiji's main update site but through the Neuroanatomy update site.
- Support for multidimensional images (including multichannel, and those with a time axis)
- A new option to perform background tracing on a second, non-displayed image
- Manual Mode: Semi-automated tracing can be temporary disabled
- Pause mode: Tracing can be interleaved with image processing routines
- Edit mode: Paths can now be edited, i.e., a path can be merged into a existing one, or split into two. Nodes can be moved, deleted, or inserted.
- Preliminary support for sub-pixel accuracy,
- New GUI with extensive options and shortcuts
- Paths can tagged, searched and filtered. Tags can be SWC fields, branch order labels, or a list of arbitrary strings. Analysis can be performed on all paths, or filtered subsets
- Paths can be color-coded by their properties: e.g., compartment, length, radii or depth
- Paths can be converted to IJ ROIs
- Masks can be generated from filled traces in a more efficient way
- Distribution command retrieves Histogram and Descriptive statistics of selected path properties
- Quick statistics command calculates common morphometric properties of traced arbors
- Detailed Horton-Strahler analysis (tabular and plotted results)
- Traces can be rendered in a rotating plot and exported as SVG/PDF
- ITK bridge
- Scripting
- Multi-threading improvements
- 3D Viewer legacy support
