3DSOMAMS [1]

3DSomaMS

The definition of the soma is fuzzy, as there is no clear line demarcating the soma of the labeled neurons and the origin of the dendrites and axon. Thus, the morphometric analysis of the neuronal soma is highly subjective. This software provides a mathematical definition and an automatic segmentation method to delimit the neuronal soma. We applied this method to the characterization of pyramidal cells, which are the most abundant neurons in the cerebral cortex. Thus, this software is a means of characterizing pyramidal neurons in order to objectively compare the morphometry of the somata of these neurons in different cortical areas and species.

Optimal Wiring [2]

CT2

The way in which a neuronal tree expands plays an important role in its functional and computational characteristics. This software enables the user to analyze the wiring optimality of a three-dimensional neuron from its specification in .asc format. The software and a user manual are available for download by clicking the link below. It takes the branching points of the real three-dimensional neuronal reconstruction and it searches for the minimal wiring arborization structure that respects the branching points. The software is capable of processing wiring design problems with point clouds up to size 200. Both dendritic and axonal wiring can be analyzed.

Voltric

Voltric [4]

Voltric is an open source software library for clustering with Bayesian networks that is being implemented by researchers of the Polythecnic University of Madrid. While still on early development, it aspires at becoming an important tool in the Data science ecosystem. Voltric provides an extensive framework for Probabilistic Graphical Models with a special focus on Bayesian networks. It equips the user with a set of state-of-the-art techniques and provide the basis for the creation of new ones.
