Abstract: The invention relates to a method for encoding of quality values of a data structure, whereby said data structure includes a plurality of continuous fragments, each continuous fragment comprises a sequence of symbols derived from a symbol alphabet and corresponds to a segment of one reference sequence of one or more reference sequences, whereby each continuous fragment is aligned to locus indexes of one of said reference sequence and at least a portion of said continuous fragments overlap at an aligned locus index, and includes, further, a plurality of quality values, each quality value is derived from a quality value alphabet and is assigned to a corresponding symbol of one of the continuous fragments, whereby each quality value indicates a likelihood that the corresponding symbol in the corresponding continuous fragment is correct, wherein the method comprises the steps executable by a data processing system: —determine the quality values at a specific locus index, which are assigned to symbols of continuou

Abstract: Embodiments of the invention are generally directed to compressing genetic sequencing data. In many embodiments, the genetic sequencing data is reordered and encoded based on sequence homology between individual sequencing reads within the genetic sequencing data. Several embodiments are directed to systems to compress genetic sequencing data, and some embodiments are directed to non-transitory, machine-readable media that direct a processor to compress genetic sequencing data. In further embodiments, the genetic sequencing data represents paired-end sequencing data, and several embodiments transmit the data to a remote device.
