Matching of the test function A to an authentic capsid structure, as well as to a similar but false structure. (A) An authentic capsid image. When the test function is deformed, the graphs illustrates how the matching function g varies with radial size ($\overline{r}$) and degree of deformation (d}) from the point in the set of admissible deformations that maximizes g. The deformed test function has an appearance similar to that of the sample, and the deformation is inside the boundaries. The classification should thus be positive. (B) Unlike (A), the point in the deformation set that maximizes g is situated on the boundary and the graphs show a higher matching value outside of this set. Thus, this classification should be negative.
