Comparison of the improvements provided by the casual and expert versions. The ratio of optimal solutions obtained with the casual version is shown in the area surrounded by a blue line, and the ratio obtained with the expert version in red. Each radar chart corresponds to one of the objective functions: Ancestor (top left), MUSCLE (top right), GUIDANCE (bottom right) and T-Coffee (bottom left). The alignment program used to calculate the initial MSAs is indicated on the axis of the radar charts: Multiz (north), MUSCLE (west), PRANK (south) and T-Coffee (east).
