The cover shows an artistic rendering of some of the results obtained through the application of the program grcarma by Panagiotis Koukos and Nicholas Glykos on page 2310 . The background surface is a color representation of the variance–covariance matrix of LmbE, a homohexameric protein. The molecular model in the foreground shows a dimer of the same protein colored according to its atomic root mean squared fluctuations.
