It sounds like you're looking for information or a community post regarding NTSYS-pc 2.02, a widely used (though older) software package for numerical taxonomy and multivariate analysis in biology.
Since "post for" could mean a few different things, here are the most common ways people look for this: 1. Help with Genetic Diversity Analysis (Most Likely)
Most researchers use NTSYS-pc 2.02 to analyze molecular marker data (like SSR, RAPD, or AFLP) to create dendrograms.
Common Goal: Converting binary data (0/1 matrices) into similarity matrices using coefficients like Jaccard or Dice.
The "Post": If you are looking for a guide, the most active discussions are on ResearchGate, where users share tips on clustering methods like UPGMA. 2. Software Download or Licensing ntsys pc 2.02 software
Status: NTSYS-pc is not free software; it was originally developed by F. James Rohlf and distributed through Applied Biostatistics Inc..
The "Post": Many users post on forums looking for "cracked" versions or free shares. However, official support and academic licenses are the only reliable way to ensure the software functions correctly on modern versions of Windows, which often require "Compatibility Mode" to run this older 2.02 version. 3. Troubleshooting or Data Formatting
Input Files: NTSYS requires a very specific .nts file format. Many "posts" online provide Excel-to-NTSYS conversion templates.
Alternatives: Because 2.02 is quite dated, many modern researchers are moving to R-Studio (using packages like adegenet or poppr) or PAST software, which is free and more user-friendly. It sounds like you're looking for information or
NTSYSpc 2.02 (Numerical Taxonomy System for Personal Computers) is a powerful, long-standing software suite used to identify and display structures in multivariate data. Originally developed for biological taxonomy, it has become a staple in fields like genetics, ecology, and morphometrics for analyzing relationships through statistical modeling and graphical visualization. Core Functionality and Applications The system is primarily used for numerical taxonomy multivariate analysis
, helping researchers find inter-correlated subsets of variables. Cluster Analysis
: Perhaps its most common application is performing agglomerative cluster analysis of similarity or dissimilarity matrices. Genetic Diversity Studies
: Researchers frequently use version 2.02 to analyze molecular data (e.g., RAPD, SCoT markers) to construct dendrograms, facilitating evolutionary studies. Biodata Implementation No GUI (graphical user interface) – command-line or
: It allows for screening large populations to select unique individuals based on the "least relativeness" for expensive downstream processes like DNA sequencing. Ordination and PCA
: The software includes tools for Principal Component Analysis (PCA), Principal Coordinates Analysis (PCoA), and multiple factor analysis to visualize complex relationships. Key Features of Version 2.02
Version 2.02 introduced several refinements over earlier iterations to better integrate with modern Windows environments:
From today's perspective, NTSYS PC 2.02 is severely limited:
ggplot2 or matplotlib.Some legacy distance coefficients (e.g., specific forms of Rogers & Tanimoto) were implemented differently in 2.02 than in modern packages. To match old results, you need the original implementation.
