Measure the amplitude of the growing mode of the matter perturbations

Hi,
I would like to know if there is a direct method for measuring the amplitude of the growing mode of the matter perturbations, D(a), and its time derivative $\dot{D}$.
If not, any sugestions to calculate these parameters from the cosmological parameters and the scale factor? Thanks in advance.

I don't have any specific suggestion, the best course of action is likely to find a paper which does the kind of analysis you are interested in, and follow the methodology described therein.
