Version 2.02 is widely regarded as one of the most stable and compatible iterations of the software. Many laboratories continue to use this specific version because it balances advanced features with a lightweight interface that runs efficiently on Windows environments. It is particularly valued for its "Matrix Comparison" feature (Mantel Test), which is essential for testing the correlation between two independent distance matrices. Key Applications

Executes Principal Component Analysis (PCA), Principal Coordinates Analysis (PCO), and Non-metric Multidimensional Scaling (NMDS) to visualize data in 2D or 3D space.

Mapping trait distributions in crop varieties to assist in breeding programs.

The name stands for "Numerical Taxonomy System," reflecting its core purpose: providing a mathematical framework for classifying organisms or objects based on measurable traits. While modern genomics has shifted many researchers toward sequence-specific tools, NTSYS-pc remains highly relevant for analyzing morphological data, ecological surveys, and molecular markers like AFLP, RAPD, and SSR.
