A Guinier analysis attempts to extract the size-scale for a structure by fitting the scattering to an equation of the form:

Thus a plot of ln(I) vs. q2 can be used to highly the scaling of the scattering. A straight-line in such a plot is indicative of Guinier scaling. Such an analysis is typically only done with the low-q portion of the data.
