a
These two cells were considered outliers, as force profiles for cell 1 displayed an attractive force, rather than a repulsive one, and the Lo value for cell 7 was grossly different from that of the other cells. Therefore, force measurements on these two bacteria were not included in the computation of average values for Lo and Γ.
b
RMSE, root mean squared error.
