The RSCU can be calculated by way of following formula: $R S C U = \frac{X_{ij}}{\sum_{j}^{ni} X_{ij}}$ where x_ij shows the frequency of codon j coding for the i^th amino acid and n_i represented the number of synonymous codon encoding the i^th amino acids. The interpretation for the RSCU is that RSCU greater than one indicates more frequency while RSCU small than 1 indicates less frequency in a gene for the particular codon. Whereas RSCU > 1.6 indicates over represented codon for the corresponding amino acid (Wong et al., 2010).
