Table 3 Mean and standard deviation values (given in parentheses, reported only for datasets with size ≥ 5) for slide for the ten dinucleotide steps containing Watson-Crick basepairs.

From: Small local variations in B-form DNA lead to a large variety of global geometries which can accommodate most DNA-binding protein motifs
