Applications

Several image processing pipelines have already been developed in MiToBo.
Below you can find selected example applications, some of them have been published already.

Neuron Analyzer 2D

The Neuron Analyzer 2D is available since release version 1.1 of MiToBo.

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

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

Note: The application is currently only available on Linux OS.
