  • Methods of detecting DNA variation in sequence data
    Patent number: 7400980
    Abstract: A method for detecting DNA variation. First, by aligning trace data of a sample DNA sequence to trace data of a reference DNA sequence to produce an aligned sample DNA sequence. Then, inputting the trace data of the bases of both the reference DNA sequence and the aligned sample DNA sequence for a particular frame number into a non-linear mathematical function of an anti-correlation calculation scheme for all the frame numbers. Minimal values will be produced at the particular frame number for DNA base trace data of the aligned sample DNA sequence which are not a variation as compared to the reference DNA sequence. Values above the minimal values will be produced at the particular frame number for DNA base trace data of the aligned sample DNA sequence which are a variation as compared to the reference DNA sequence.
