Non-contiguous regions of interest as well as contiguous regions of interest are similarly processed. After an isotope peak detector has identified isotope peaks on LC/MS images, a microaligner microaligns bounding areas of identified isotope peaks and redefines the bounding areas to help subsequent scoring process. Forms of isotope peaks influence formation of a peak association matrix and a mass/charge association map which creates association in the mass/charge dimension. A correlation scorer produces reproducibility scores as well as quality scores to help aid scientists to discover biological features of interest.
