Algorithm 2SNR-SE

Input: DNA sequence s Output: One sided spectrum $S\left[k\right]$  1:$sn{r}_{ref}\leftarrow -\infty$  2:foreachkin$[0,\lfloor \raisebox{1ex}{$N$}\!\left/ \!\raisebox{-1ex}{$2$}\right.\rfloor ]$do  3:   $\mathbf{w}\leftarrow$SpectralEnvelope (s, k)  4:   ${\mathcal{M}}_{ref}\leftarrow$ map whose image are the components of $\mathbf{w}$  5:   Compute $S\left[k\right]$ using Equation (11)  6:   $snr\leftarrow \mathrm{SNR}\left(S\right[k\left]\right)$  7:   if $sn{r}_{ref}<snr$ then  8:       $sn{r}_{ref}\leftarrow snr$  9:       $\mathcal{M}\leftarrow {\mathcal{M}}_{ref}$ 10:   end if 11:end for 12:Compute $S\left[k\right]$ using (11) and $\mathcal{M}$ 13:return $S\left[k\right]$
