The Kidera Factors were originally derived by applying multivariate analysis to 188 physical properties of the 20 amino acids and using dimension reduction techniques. A 10-dimensional vector of orthogonal factors was then obtained for each amino acid.

Calculate physicochemical properties and indices from amino-acid
sequences of peptides and proteins. Include also the option to read and plot
output files from the 'GROMACS' molecular dynamics package.

A list with the ten Kidera factors of the 20 amino acids. The first four factors are essentially pure physical properties; the remaining six factors are superpositions of several physical properties, and are labelled for convenience by the name of the most heavily weighted component.
