Abstract
Method and system for the transmission of genomic data. The transmission of genomic data is realized by employing the multiplexing of a structured compressed genomic dataset in a stream of genomic data partitioned into randomly accessible access units.
Claims12
A method for the transmission of genomic data as multiplexed data streams comprising:
- a genomic dataset list data structure for providing a list of all genomic datasets, said genomic datasets comprising genomic data available in genomic streams;
- a genomic dataset mapping table data structure for providing an identifier of each stream of said genomic data associated to each genomic dataset;
- wherein the genomic datasets are partitioned into selectively accessible access units according to a classification of genomic data contained in each genomic dataset, said classification based upon a type of difference between a read and a reference genome;
- wherein said genomic streams comprising encoded aligned reads organized as homogeneous data descriptors to univocally represent genome sequence reads,
- wherein each of said genomic streams adopts an entropy coder to store said homogenous data descriptors in layers partitioned into said selectively accessible access units;
- wherein in each access unit it is stored a mapping position of a first read of said access unit as an absolute position with respect to a reference genome, and
- all the other positions are expressed as a difference with respect to a previous position,
- said method comprising:
- compressing said homogeneous data descriptors,
- multiplexing said compressed homogeneous data descriptors from said data streams, and
- transmitting said data.

Method for receiving genomic datasets comprising genomic data, the method comprising:
- receiving multiplexed data streams representative of genomic datasets;
- extracting, from the multiplexed data streams, a genomic dataset list data structure which provides a list of all genomic datasets, said genomic datasets comprising genomic data available in the genomic streams;
- extracting, from the multiplexed data streams, a genomic dataset mapping table data structure which provides the identifier of each stream of said genomic data associated to each genomic dataset;
- extracting, from said multiplexed data streams, compressed homogeneous data descriptors according to a classification of genomic data contained in each genomic dataset, said classification based upon a type of difference between a read and a reference genome;
- decompressing said homogeneous data descriptors, thereby obtaining aligned reads which univocally represent genome sequence reads;
- extracting, from the multiplexed data streams, selectively accessible access units;
- obtaining, from said access units, the genomic datasets;
- wherein each of said multiplexed data streams adopts an entropy coder to store said homogenous data descriptors in layers partitioned into said selectively accessible access units
- wherein in each access unit it is stored the mapping position of the first read as absolute position with respect to the reference genome and all the other positions are expressed as a difference with respect to the previous position.
