Properties of the relation between two residues

Properties of relations involving a O3'-P covalent bond:

	stack	$$	Stacking
	nostack	$$	No stacking (deprecated, use !stack)
	reverse	$$	Reverse stacking
	connect	$$	Any covalently bonded relation (stack+!stack) (deprecated, use adjacent)
	helix	$$	Standard A-Form double helical stacking

Properties of relations for paired residues:

	pairing	$$	All pairing interaction
	<I to XXVIII>	$$	Pairing described by Saenger
	saenger	$$	All of the above
	<29 to 137>	$$	One-H-bond pairings described by Gautheret
	one_hbond	$$	All of the above One-H-bond
	theo	$$	Only theoretical (planar) pairing
	cis	$$	Glycosyl bonds are in the same orientation relative to the mean orientation of H-bonds
	trans	$$	Glycosyl bonds are in opposite orientation relative to the mean orientation of H-bonds
	wct	$$	Watson-Crick pairing used to build standard A-form helix

	Hh	$$	center of the Hoogsteen face involved
	Hw	$$	Hoogsteen face involved, near the Watson-Crick face
	C8	$$	Hoogsteen face involved, near the C8 atom
	S	$$	Sugar face involved: (Sw $\vert\vert$ Ss)
	Sw	$$	Sugar face involved, near the Watson-Crick face
	Ss	$$	center of the Sugar face involved
	B	$$	Bifurcated face involved
