Figure 4From: ReXSpecies – a tool for the analysis of the evolution of gene regulation across speciesFrom annotated alignment to bitmap. A feature bitmap based on TFBS predictions. The annotated alignment is converted to a bitmap (an array with entries 0 or 1). Each column corresponds to a TFBS at a specific position in the alignment, each row to a sequence. An entry is 1 if the sequence is predicted to contain the TFBS and 0 otherwise.Back to article page
