Finding motifs with reads from Round 4 by using MEME.

<p>Five motifs were extracted for each of five samples containing various numbers of non-overlapping 16-mer reads from Round 4. The top four motifs were displayed above the histogram of their fold enrichments. M1 to M4, Motif 1 to motif 4. FE, fold enrichment. The title of Y-axis of motif logos was “bits” and the labels were 0, 1 and 2. The labels under the motif logos were “1” to “10” from left to right that referred to the positions of nucleotides in a motif.
