The invention relates to a computer-implemented method for classifying events present in a sample, wherein each event is characterized by a multidimensional set of parameters obtained by means of hardware and/or software, wherein the values of the parameters associated with each event define the position coordinates of said event in a multidimensional space. Said method comprises the following stages: a) clustering the events in groups, b) checking if within each formed group there is a connection between events exceeding a maximum distance threshold, c) calculating the affinity between each pair of previously generated sample groups, d) comparing each sample group with at least one reference group stored in at least one database, e) classifying the sample groups based on the comparisons with the reference groups.
