The two- and three-dimensional trianders are considered.
Determinative degree and nucleotide sequence analysis by trianders
The topological classiﬁcation of trianders is presented which can allow us to provide a detail working out signatures of functionally different genomic regions.
Determinative degree and nucleotide sequence analysis by trianders
Obviously the ideal triander for uniformly random sequence consists of 3 ﬂowing together lines from the origin having 45 degrees slope.

Such lines are presented on all triander plots below for normalization.

As the measure of the “sequence strength” we can choose length of the radiusvector from the origin to the current point of triander, i.e. the Euclidean distance DE (i) = q(4nC (i) − 3nG (i))2 + (2nT (i) − nA (i))2 .
