Cell image analysis system

A cell image analysis system comprising:

• a data tree creator configured to create a plurality of data trees relating to cell images by classifying the cell images into a plurality of groups each of which includes the cell images that have common classification information;
• a data tree storage configured to store the plurality of data trees created by the data tree creator;
• a graph creator configured to create a graph relating to a first data tree that is selected by a user, and having classification information of a bottom layer or a second layer from the bottom layer of the first data tree as a horizontal axis parameter and analysis results of the cell images that are included in the first data tree as a vertical axis parameter;
• and
• a display controller configured to display the graph created by the graph creator,
• a data tree searcher configured to search for a second data tree from among the plurality of data trees stored in the data tree storage based on a search condition relating to cell culture and different from classification information, wherein
• the display controller is configured to display the second data tree that is different from the first data tree and has common horizontal and vertical axis parameters to the first data tree in the plurality of data trees stored in the data tree storage to be selectable by the user, and, when the second data tree is selected by the user, to update the graph by adding the analysis results of the cell images that are included in the second data tree selected by the user to the graph.
