The human genome is composed of large-scale compartmentalized structures, including long G+C% (GC%) mosaic structures and replication-timing zones, which are related to chromosome band zones. Previously, we measured replication timing along the entire lengths of human chromosomes 11q and 21q at the sequence level, and it was suggested that the transition regions of replication timing from early to...
Novel tools are needed for comprehensive comparisons of interspecies characteristics of massive amounts of genomic sequences currently available. An unsupervised neural network algorithm, Self-Organizing Map (SOM), is an effective tool for clustering and visualizing high-dimensional complex data on a single map. We modified the conventional SOM, on the basis of batch-learning SOM, for genome informatics...
With increases in the amounts of available DNA sequence data, it has become increasingly important to develop tools for comprehensive systematic analysis and comparison of species-specific characteristics of protein-coding sequences for a wide variety of genomes. In the present study, we used a novel neural-network algorithm, a self-organizing map (SOM), to efficiently and comprehensively analyze...
