Name of Plugin/Operator:
NeuronAnalyzer2D (since MiToBo version 1.1)

Main features:

  • Neuron boundary detection based on active contours
  • Identification of structural neuron parts, like soma, neurites and growth cones
  • Morphology analysis, e.g., neurite length, average neurite width, number of branch and end points, growth cone size and shape roundness, etc.
  • Extraction of molecular profiles from fluorescently labeld molecules
  • Detection of molecular particles, for example FISH data

Installation:

The R software environment (http://www.r-project.org/) must be installed to use the Neuron Analyzer 2D.
If R is installed on the system, two environment variables must be set. Perform the following steps on the commandline to set the variables:

  1. export R_HOME="/usr/lib/R" # path to your R installation
  2. export R_SCRIPTS="/path/to/ImageJ/share/scripts/R" # path to the R scripts, shipped with MiToBo zip file
  3. libjri.so must be in the LD_LIBRARY_PATH

To save these variables permanently, copy the commands above to your local .bashrc file.

Note: The application is currently only available on Linux OS.
Current version of Neuron Analyzer 2D uses R version 3.0.2 (2013-09-25) with rJava_0.9-5 (jri_0.5-5)
