Identification of Protein-Coding Regions in DNA Sequences Using A Time-Frequency Filtering Approach

Abstract: Accurate identification of protein-coding regions (exons) in DNA sequences has been a challenging task in bioinformatics. Particularly the coding regions have a 3-base periodicity, which forms the basis of all exon identification methods. Many signal processing tools and techniques have been applied successfully for the identification task but still improvement in this direction is needed. In this paper, we have introduced a new promising model-independent time-frequency filtering technique based on S-transfor… Show more

“…In addition to digital filter-based approaches for periodicity detection [34,35], some statistical properties [36,37] are often integrated into signal processing methods for detecting the regularities in genetic codes (e.g., codon useage, hexamer counters, codon position asymmetry, different periodicities, autocorrelations, nucleotide frequencies, entropy measures, and so forth).…”
