This file was used to look for a treatment (F1 and F2) on morphology (shape and size). Columns included are: "centroid" = size, "Dvpop" = divergence vector, "line" = maternal line, "treatment" = F2 treatment (C = control, P = predator), "ptreatment" = F1 treatment (C = control, P = predator), "numberincup" = snail density in home arena
