Abstract:
1. A method for positioning with at least one computing device multiparameter cellular analysis data from a particle analyzer, comprising: (a) using the at least one computing device, performing a cross-correlation between pixel data in a target sample data and pixel data in a template data to measure a similarity between pixel data in the target sample data and pixel data in the template data, wherein the target sample data represents values of at least two different measured parameters for a set of cells that have been analyzed with the particle analyzer, and wherein the template data represents values of the same at least two parameters for a cell population of a known type; (b) generating a cross-correlation image based on the performed cross correlation, wherein pixels in the cross-correlation image have intensities depending on the similarity between the pixel data in the target sample data and the pixel data in the template data; (c) using the at least one computing device, determining a pixel location in the cross-correlation image corresponding to a substantially maximum intensity in the cross-correlation image and setting an offset position based on the pixel location; and (d) using the at least one computing device, shifting locations of the pixel data in the template data with respect to at least one of the at least two different measured parameters based on the offset position to produce shifted template data having pixel data at shifted locations that match the corresponding pixel data in the target sample data.
