GENERATING AND USING A STATE TRANSITION MATRIX FOR DECODING DATA IN A DNA-BASED STORAGE SYSTEM

Abstract: a state transition matrix for a data storage system indicates a reliability of data that was read or decoded from a data storage channel. the state transition matrix includes a probability of reading each state of a nucleotide base in an identified storage material when that nucleotide base was initially programmed in a particular state. the state transition matrix is generated by identifying a storage material with the most copies in the data storage system. during a sequencing process, the identified storage material is decoded, corrected and compared against the storage material that was originally synthesized. this information is used to determine the probability values for the state transition matrix. the state transition matrix is provided to an error correction system of the data storage system, which uses the probability information when determining whether decoded data of other storage materials should be corrected.
