Figure 1

An example of sequence logo representation for chromatin state CS3 (derived from [3]) in Arabidopsis, inferred from tiling arrays of 12 chromatin marks. Each stack represents the distribution and information content (in bit scores, blue dash line indicates the maximum bit score) of chromatin signatures with Low, Medium or High intensities within a cluster of regions with similar signatures. The bar below is adapted from [3]: colors indicate the distribution of chromatin marks from 25% (light-) to 100% (dark purple); numbers inside cells indicate the percentage of tiles that are associated with each chromatin mark and assigned to the CS3. The logos are generated using Weblogo 3.2 program [4]. The epi-letters for 5mC are enlarged in the inset.
