Structure Analysis
Purpose
Structure Analysis is a set of python modules for the analysis of structured data issued from plant phenotyping. It is part of OpenAlean and mainly dedicated to the statistical analysis of graphs, trees and sequences but also includes computational methods for tree matching. Sequence analysis is based on hidden semi-Markov and variable-order Markov chains1. Tree analysis is based on hidden Markov trees2. Tree matching offers possibilities of accounting for different metrics and constraints3. …
