I applied croissance to analyze growth curves of Pseudomonas aeruginosa grown on glycerol and the exponential phases identified by Croissance seem to include lag phases (and gives 0 lag time). I have attached a figure where the identified exponential phases are shown in shaded blue (rank 1st) and shaded green (rank 2nd). You might see that in most cases, the identified exponential phase is extended to the origin of time and thus includes lag phase. Technically, I constrained n0 to be zero and the y axis was plotted on the log scale. Do you think this is an issue and, if it is, what causes it?
