Secondary-structure patterns

Find stretches of secondary structure in a given arrangement across every analysed chain.

• Regular expressions over H, E and L or DSSP's eight states
• Presets: β-hairpin, β-α-β, helix–turn–helix, helix–loop–helix, β-meander, α-hairpin
• A sequence motif the stretch must hold, and the strands' pairing

Secondary structure assigned as DSSP 4 does.
