The sequence order …". (3) Equation 10 should read as $$ \bar{x}_{i}^{\xi}=\frac{1}{n_{\xi}}\sum_{k=1}^{n_{\xi}}x_{k,i}^{\xi},\qquad(i=1,2,\ldots,20+\lambda). $$erratum # Prediction of Protein Cellular Attributes Using Pseudo-Amino Acid Composition Kuo-Chen Chou Computer-Aided Drug Discovery, Pharmacia, Kalamazoo, Michigan PROTEINS: Struct Funct Genet 2001;43:246–255 (1) All the symbols λ in Figure 1 of page 247 should be replaced by Θ, as shown in the following figure: (2) Right after Equation 1 of the same page, the following words should be inserted: "where R₁ represents the residue at sequence position 1, R₂ the residue at position 2, and so forth.
