Example results of data from calcium spiking. A: Time series of Ca2+ oscillations measured in a M. truncatula root hair cell in response to a bacterial signal molecule. The data is a relative ratio of the fluorescence of the Ca2+ indicator dyes Oregon Green and Texas Red, showing changes in concentration, [Ca2+]. The measurements are taken with 5 s intervals. BSA identifies one strong frequency at a period, T, of about 100 s (C), while MTM (B) and FFT (D) deliver a broad spectrum.
