Statistical analysis of size distributions of VLPs and cores obtained through automated image analysis.

<p>The number of particles is indicated by the value <i>N</i>. <i>(a)</i> and <i>(c)</i> 2D histograms of short and long diameters for respectively mature VLPs and cores. <i>(b)</i> Short diameter histogram obtained by projecting the 2D histograms for VLPs and cores. <i>(d)</i> and <i>(f)</i>, long diameter histogram obtained projecting the 2D histograms for VLPs and cores. <i>(e)</i> Typical example of short and long diameters measured on a single particle.
