Table 2.

Occurrence of shapes in results with at least 20 bit each

m₁	`_`	`[]`	`[][]`	`[][][]`	`[[][]]`	Complex
m₂	`_`	`[]`	`[][]`	`[][][]`	`[[][]]`	Complex
Found	19 644	49 289	1576	40	12	28

Unstructured regions (dashes) and hairpins (square brackets) as the common region occur most often. The other shapes show that complex substructures can form. The high number of lone hairpin structures is a direct consequence of the huge meta-family of snoRNAs which have a simple secondary structure. Under ‘complex’, all structures that did not fit into the given shapes were collected.
