Agna is a platform-independent application designed for social network analysis, sociometry and sequential analysis.

This software can help you if you study communication relations in groups, kinship relations or the structure of animal behavior - to mention just a few realms where it can be used.

Agna allows you to create, edit, analyze, store, and visualize networks. Agna also enables you to create networks from (behavioral) chains.

Network analysis (or social network analysis) is a set of mathematical methods used in social psychology, sociology, ethology, and anthropology.This methodology assumes that the way the members of a group can communicate to each other affect some important properties of that group (such as performance, leadership, work satisfaction etc.)

Sequential analysis deals with behavioral chains.After recording the behavior of an animal in specific conditions, the ethologist divides the whole behavioral chain into basic sequential units/codes.
