Patent ID: 7006925

Claim:
A method of data analysis for determining a base sequence for nucleic acid, based on detected data of electrophoresis of a fragment sample of nucleic acid, comprising steps of: (A) performing waveform shaping by Fourier transformation on data of a certain number N of points from the head of the detected data using a predetermined peak interval as a parameter; (B) determining the base sequence as to data of P points (P<N) from the head of the data of N points; (C) obtaining a subsequent peak interval from the result of the sequence determination in the most recent base sequence determination step; (D) performing waveform shaping by Fourier transformation on data of N points starting from a position returning by L points (L<M) from a final point of the data subjected to the sequence determination in the most recent base sequence determination step using the subsequent peak interval of the most recent step (C) as a parameter; and (E) determining the base sequence as to data of M points (M<N) of a central portion among the data of N points subjected to waveform shaping in step (D), so as to be connected with data most recently subjected to the sequence determination, wherein the steps (E)→(C)→(D) are repeated until all data has been analyzed or no analysis is required despite presence of data, and (F) determining a base sequence of nucleic acid by connecting sequence-analyzed portions.
