ENHANCED DATA COMPRESSION FOR SPARSE MULTIDIMENSIONAL ORDERED SERIES DATA |
摘要 |
Disclosed are methods and systems for significantly compressing sparse multidimensional ordered series data comprised of indexed data sets, wherein each data set comprises an index, a first variable and a second variable. The methods and systems are particularly suited for compression of data recorded in double precision floating point format. |

1. A computer-implemented method of compressing a sparse multidimensional ordered series of spectroscopic data, the method comprising:
a) receiving the sparse multidimensional ordered series data containing values that fall within a dynamic range of less than 10 orders of magnitude, wherein the data comprise indexed data sets, each indexed data set comprising an index (n), a first variable (xn) representing a mass to charge ratio (m/z), and a second variable (yn) representing signal intensity; b) defining a predictor that calculates each first variable (xn); c) assigning an amplitude code word to each yn; d) calculating a hop offset value (Δn) for each yn; e) assigning a hop code word to each Δn based on the value of the Δn; and f) generating a compressed output, said compressed output comprising:
i) a decoder legend comprising:
a reverse amplitude code word dictionary associated with yn; anda reverse hop code word dictionary associated with Δn; andii) code word data comprising an amplitude code word and a hop code word for each yn and each Δn. |
