Abstract

The invention provides a melting curve abnormal value processing method and device and electronic equipment, and relates to the technical field of data detection, and the method comprises the steps: obtaining amplified fluorescence intensity data in a PCR melting process, carrying out the detection of the fluorescence intensity data in a mode of continuous wavelet transformation, and determining the position of an abnormal value; in the preset neighborhood range where the abnormal value position is located, carrying out linear fitting on the fluorescence intensity data according to the variable window value, obtaining a fitting curve, carrying out polynomial fitting derivation on the fitting curve, determining a melting curve, and solving the technical problem that a high-precision melting curve cannot be obtained.

Description

technical field [0001] The present application relates to the technical field of data detection, in particular to a method, device and electronic equipment for processing abnormal values ​​of melting curves. Background technique [0002] At present, the standard nucleic acid quantification method for diagnosing infectious diseases mostly uses fluorescent real-time quantitative PCR, which can quantify the initial value of the sample template, and is often used in gene analysis and expression, genetically modified food detection and cancer detection. [0003] However, in the current actual data debugging, the fluorescence intensity occasionally has abnormal values, and the existing methods cannot deal with the abnormal values ​​of the melting curve, which is the change value of the fluorescence intensity, and it is difficult to determine the smoothed melting curve. The current method cannot obtain Higher precision melting curve. Contents of the invention [0004] The purpos...
