Sliding-window analysis has widely been used to uncover synonymous (silent. d(S)) and nonsynonymous (replacement. d(N)) rate variation along the protein sequence and to detect regions of a protein under selective constraint (indicated by d(N)d(S)). The approach compares two or more protein-coding genes and plots estimates d(/\)(S) and d(/\)(N) from each sliding window along the sequence. https://www.markbroyard.com/discount-rainbow-it-s-my-birthday-satin-sash-for-cheap-hot-grab/
