Relative Stability of Transcripts of Adjacent Co-directional Genes

The relative stability is defined as $1-\left(\left|t_{up}-t_{down}\right|/\left|t_{up}+t_{down}\right|\right)$, with $t_{up}$ and $t_{down}$ the transcript half-lives of the upstream and downstream genes, respectively; this parameter is therefore close to 1 for similar half-lives and close to 0 for very different ones. The red bands indicate the SEM computed over the corresponding region of co-expression. The gray bands indicate the same values but for a random set of pairs of genes.
