%description
Provides an implementation of the framework of reversed graph embedding
(RGE) which projects data into a reduced dimensional space while
constructs a principal tree which passes through the middle of the data
simultaneously. DDRTree shows superiority to alternatives (Wishbone, DPT)
for inferring the ordering as well as the intrinsic structure of the
single cell genomics data. In general, it could be used to reconstruct the
temporal progression as well as bifurcation structure of any datatype.
