Representability of genomic signals.
The paper presents a simple novel approach to data representability, based on the concept of relative data variation for a pixel. Typical cases of signals are analyzed from the representability point of view, with the focus on genomic signals. It is shown that the variation of genomic data along nucleotide sequences, specifically the cumulated and unwrapped phase of complex genomic signals, can be visualized adequately as simple lines for low and large scales, while for medium scales (up to several hundred samples per pixel) the approach used for statistical data representation must be used.
