Hi Jessie, There is no way to keep the age axis fixed when generating randomly perturbed faces in the 'Genetic' tab.
As you point out, the best way is to manually adjust the age of each perturbed sample back to where you want it. Note that the random perturbations added in the 'Genetic' tab are multivariate normally distributed in face space, so the magnitude of the perturbations are not completely fixed but in fact follow a chi-squared distribution (with 130 DOF over shape and color), with mean proportional to the 'Randomness' value. Further, even if they were fixed magnitude perturbations, there is no guarantee they are proportional to perceptual measures of difference as they are defined by squared differences.
