I don't like the shape of a certain spot. Can't I draw it like I want?
According to Good Lab Practice, results should be reproducible and unforgeable. This would not be the case if Delta2D would allow for drawing spots arbitrarily. Due to this, Delta2D enables you to draw markers indicating your corrections (e.g. if you see clearly that two spots detected as individuals are both part of the same spot and you want to have them detected as one spot), but the spot shapes themselves still are detected by Delta2D, only following your indications.
