DFT provides a robust detection method for higher order periodicity and is robust with respect to monomer insertions and deletions, random sequence insertions etc.
Abstract
Background Identification of approximate tandem repeats is an important task of broad significance and still remains a challenging problem of computational genomics. Often there is no single best approach to periodicity detection and a combination of different methods may improve the prediction accuracy. Discrete Fourier transform (DFT) has been extensively used to study primary periodicities in DNA sequences. Here we investigate the application of DFT method to identify and study alphoid higher order repeats.

Long-range correlations in nucleotide sequences

TL;DR: This work proposes a method for studying the stochastic properties of nucleotide sequences by constructing a 1:1 map of the nucleotide sequence onto a walk, which it refers to as a 'DNA walk', and uncovers a remarkably long-range power law correlation.

TL;DR: The sequence of the euchromatic part of human chromosome 22 is reported, which consists of 12 contiguous segments spanning 33.4 megabases, contains at least 545 genes and 134 pseudogenes, and provides the first view of the complex chromosomal landscapes that will be found in the rest of the genome.

Recognition of protein coding regions in DNA sequences

TL;DR: The test has been thoroughly proven on 400,000 bases of sequence data: it misclassifies 5% of the regions tested and gives an answer of "No Opinion" one fifth of the time.

The mosaic genome of warm-blooded vertebrates.

TL;DR: This approach has revealed that the distribution of genes, integrated viral sequences, and interspersed repeats is highly nonuniform in the genome, and that the base composition and ratio of CpG to GpC in both coding and noncoding sequences, as well as codon usage, mainly depend on the GC content of the isochores harboring the sequences.
