From: BESST - Efficient scaffolding of large fragmented assemblies
Notation. a) A read pair with insert size x (unknown distance) aligns to two contigs c
a
and c
b
, thus creates a link between c
a
and c
b
. The read pair gives rise to observations o
a
,o
b
and they are used to infer the unknown distance d. Distances for o
a
,o
b
,d and r are illustrated. b) Graph structure and notations of the scaffold graph 
. Two contigs c
a
and c
b
connected by an edge e created from alignments of read pairs.
