Abstract: A method of analysing a plurality of biological entities using an imaging apparatus. The method comprises: providing a marker for said plurality of biological entities, said marker being capable of identifying objects within said plurality of biological entities when detected using the imaging apparatus, the method of provision being arranged such that said marker is capable of identifying said objects during a first time period, and said marker is less capable of identifying said objects during a second time period; during the first time period, recording a marked-up image in which spatial definitions of said objects are identifiable from said marker; during the second time period, recording a first image of said plurality of biological entities; and generating a spatial definition for an object in said first image using data derived from said marked-up image.

Abstract: A method of determining cell cycle phase data for cells comprising at least one luminescent reporter capable of emitting radiation, the at least one luminescent reporter comprising a first luminescent reporter which is capable of being indicative of at least one cell cycle phase, said method comprising: storing classification information for classifying individual cells into different cell cycle phases using an automated classification process; receiving image data created by detecting radiation emitted by said at least one luminescent reporter; analyzing said image data to identify object areas in the image data which correspond to individual cells; analyzing said image data, on the basis of said identified object areas, to determine, for a selected cell, one or more measurements including a measurement of a parameter relating to at least a cytoplasmic component of the cell; and applying said classification information to said measurements to classify the selected cell into a selected one of a plurality of s
