CIS - Calculating the Consensus Informational Spectrum (cross-spectrum)
ISM technique allows the detection of code/frequency pairs which are specific for their common biological properties, or which correlate with their specific interaction. These common informational characteristics of sequences are determined by cross-spectrum or consensus informational spectrum (CIS).

ISTREE - Building the Informational Spectrum-based Phylogenetic Tree
For phylogenetic analysis we are using the new distance measure based on the informational spectrum (IS). This new approach in phylogenetic analysis allows at first time the assessment of functional viral evolution.
