Methods are provided that operate on raw dissociation data and dissociation curves to generate calibrations of the detected data and to further improve analysis of the data. The data can be taken from each support region of a multi-region platform, for example, from each well of a multi-well plate. Each support region can be loaded with portions of the same sample. In some embodiments, a dissociation curve correction can be calibrated for the sample, prior to a run of an experiment using such sample. In some embodiments, a method is provided for generating a melting transition region of dissociation curves that show the melting characteristics of the sample. In some embodiments, dye temperature dependence correction can be performed on the dissociation curve data to further improve analysis. In some embodiments, a feature vector can be derived from the melt data, and the feature vector can be used to further improve genotyping analysis of the dissociation curves.

A heater plate includes a sheet-like heating member that generates heat upon being energized, a protective film provided on the side of one major surface of the sheet-like heating member to protect the sheet-like heating member, an output circuit section provided on a surface of the protective film on the opposite side to the sheet-like heating member, and a protruding portion forming film provided between the protective film and the sheet-like heating member. The output circuit section has protruding portions formed to be capable of respectively abutting terminals of a heat flux sensor which is an inspection object. The protruding portion forming film has protrusions at positions corresponding to the protruding portions. The sheet-like heating member, the protective film, the output circuit section and the protruding portion forming film are integrally formed into one piece.
