In a first aspect, a method for use in biology, histology, and pathology, comprises: providing a digital first image (44) of a first slice (12) of an object (10) comprising biological material; generating a digital second image (46) of a second slice (14) of the object; determining a region of interest (50) in the second image on the basis of a region of interest (48) in the first image; determining a region of interest in the second slice on the basis of the region of interest (50) in the second image; and extracting material from the region of interest in the second slice. In another aspect, an information processing system, for use in biology, histology and pathology, comprises: a predefined set of process identifiers (64); a set of data records (68, 70, 72) associated with an object (10) comprising biological material, wherein each of the data records comprises: a slice identifier identifying a slice (12; 14) of the object, and a process identifier selected from the set of process identifiers, the process identifier indicating a process to which the slice is intended to be subjected; a user interface (52, 56, 58, 60) for enabling a user to select a data record (68) from the set of data records.
