Abstract
Functionality is described for compressing and decompressing mass spectrometry data, therefore making it easier to store, retrieve, transfer, and process the mass spectrometry data. The functionality operates by mapping data values (e.g., mass-to-charge data values or intensity data values) into index values, and then mapping the index values into delta values. The functionality then uses an encoding algorithm (such as a coding tree) to represent the delta values in compressed form. In a decoding stage, the functionality can interpret each encoded delta value with reference to a chain of preceding delta values, which ultimately link to an initial data value that is expressed in non-relative form. In one implementation, the functionality can define multiple such initial data values which correspond to multiple access points in a stream of compressed mass spectrometry data.
