However, I must let you know that:

Proximity and Distance MatricesBefore creating a visual tree or cluster, the software must calculate how similar or different each sample is from the others. NTSYSpc contains a vast library of coefficients to achieve this. For qualitative or binary data (such as presence/absence data in ecology), it computes coefficients like Jaccard, Dice, or Simple Matching. For quantitative or continuous data (such as anatomical measurements), it utilizes Euclidean distance, Manhattan distance, or correlation coefficients.

NTSYSpc uses a rigid file format, typically requiring an NT-format text file (.nts). A standard workflow consists of the following steps:

stands for N umerical T axonomy S ystem for the PC . Developed by Exeter Software, it is a statistical package designed specifically for the analysis of multivariate data. Unlike general statistical software like SPSS or SAS, which are broad in scope, NTSYS is highly specialized. It focuses on the classification of items (often organisms, populations, or gene sequences) based on similarities and distances.

Reduces high-dimensional data into 2D or 3D plots.

NTSYSpc 2.02 is used across multiple scientific disciplines due to its flexibility with matrix structures:

I understand you're looking for the software.
