Figure 2
Relationship between the AUSPEX plot (bottom; PDB entry 4epz) and the Helcaraxe plots (top), which are 80 × 80 pixel histograms of the respective areas. Helcaraxe axis labels refer to pixel numbers. Ice-ring features were automatically identified by the statistical AUSPEX Icefinder score (shaded pink bars). The grey bars in the AUSPEX plot indicate the resolution ranges in which an ice ring can appear (letters A–H) that are used to generate the focused plots (top). The rectangles indicate the areas that the upper plots display. Helcaraxe plots E and H show ice-ring characteristics (spikes), while plot D shows none.
