Abstract
Abstract A method and apparatus for the processing of DNA sequence image data in real time is implemented using a series of linked neural network processors. As raw image data is received from a sequencing machine, it is buffered and then separately transformed in real time in the processors to enhance the signals indicative of the unknown DNA sequence. A fourth processor receives the transformed data and determines and reports the sequence indicating events.
