Methods and apparatus for analyzing embryo development

Apparatus and methods for helping a user establish values (e.g. timings) for a plurality of parameters of target (e.g. cell divisions) relating to the development of an embryo from a series of images of the embryo are described. For each parameter of target an image is selected for display to a user seeking to establish a value for the parameter of target. For example, the selected image may be an image predicted to be an image reflecting the value for the parameter of target. For example, the selected image may be based on a calculated timing for a particular developmental event. The timing may be calculated from a numerical analysis of the images or maybe predetermined. If the user is unable to determine a value for the parameter of target from the selected image, the user may scroll through neighboring images until the user can determine a value for the parameter of target. A value for the proud of target may then be established in response to user input, for example a user providing an indication that a t
