Classification methods of DNA most commonly use comparison the differences in symbolic records, which requires global multiple sequence alignment. This solution is often inappropriate, causing a number imprecisions and additional user intervention for exact alignment similar segments. The segments represented as signal are characterized by shape curve. genomic signals may adjust whole sections not only individual symbols. dynamic time warping (DTW) suitable this purpose can replace sequences...

Visualization analysis plays an important role in metagenomics research. Proper and clear visualization can help researchers get their first insights into data by selecting different features, also revealing highlighting hidden relationships drawing conclusions. To prevent the resulting presentations from becoming chaotic, techniques have to properly tackle high dimensionality of microbiome data. Although a number methods based on reduction, correlations, Venn diagrams, network...

Large-scale comparative studies of DNA fingerprints prefer automated chip capillary electrophoresis over conventional gel planar due to the higher precision digitalization process. However, determination band sizes is still limited by device resolution and sizing accuracy. Band matching, therefore, remains key step in fingerprint analysis. Most current methods evaluate only pairwise similarity samples, using heuristically determined constant thresholds maximum allowed size deviation;...
