For each data sample, two trees and four subtrees were considered: a an example of a starting tree; b, c the two subtrees induced by the pruned branch of a tree a (in red), where b is the pruned subtree and c the remaining subtree; c1c2 the regrafted branch (in blue) also induces two subtrees, from both sides of the regrafted branch of subtree c; d the resulting tree following the SPR move.
