Graphical output of the SWGIS v2.0 algorithm. The SWGIS v2.0 displays GIs (pink blocks) on large linear chromosomes. Several parameters are also shown on the graph: GC-content (black curve); ratio of generalized to local relative variances calculated for tetranucleotide usage patterns normalized by the GC-content (blue curve, n1_4mer:GRV/n1_4mer:RV); distances between not-normalized local tetranucleotide usage pattern and the global pattern calculated for the complete chromosome (red curve, n0_4mer:D); asymmetry between not-normalized tetranucleotide usage patterns calculated for the direct and complement DNA strands (green curve, n0_4mer:PS). Use of these parameters for GI identification and their standard abbreviations were explained in more detail by Ganesan et al. (2008). and on the EuGI website (http://eugi.bi.up.ac.za) [25]
