Figure 1From: SIGffRid: A tool to search for sigma factor binding sites in bacterial genomes using comparative approach and biologically driven statisticsMerging of upstream overlapping sequences on a same strand. The final statistical test of motifs needs to count the number of occurrences in the upstream sequences. If genes overlap each other, their upstream sequences could overlap each other. We avoid to count twice the same motif occurrence by merging upstream overlapped sequences which are on a same strand.Back to article page
