Abstract
PolySNAP3is a computer program for the classification of powder diffraction, spectroscopic and numerical data either separately or combined. A correlation matrix is generated by matching full data profiles; for numerical data the standard Euclidean distance is calculated. The matrices are combined by the INDSCAL method [Carroll & Chang (1970).Psychometria,35, 283–319] to give either a single interpretation of the data or combinations of any of the data types. Cluster analysis, multivariate data analysis and extensive data visualization routines are used to automatically classify the patterns into groups, validate the classification, and thus identify polymorphs, mixtures and salts.
