Abstract
In an aspect, a method for evaluating the partitioning of nucleic acid molecules in a sample of polynucleotides based on epigenetic state, comprising: (a) adding a set of epigenetic-control nucleic acid molecules to the nucleic acid molecules in the sample of polynucleotides, whereby producing a spiked-in sample; (b) partitioning nucleic acid molecules of the spiked-in sample into plurality of partitioned sets; (c) enriching a subset of molecules from the plurality of partitioned sets to generate enriched molecules, wherein the enriched molecules comprises a group of epigenetic-control nucleic acid molecules and a group of nucleic acid molecules from the sample of polynucleotides; (d) sequencing the enriched molecules to produce sequencing reads; (e) analyzing the sequencing reads to generate one or more epigenetic partition scores of the epigenetic-control nucleic acid molecules; and (f) comparing the one or more epigenetic partition scores with one or more epigenetic partition cut-offs.

39. A method for evaluating partitioning of nucleic acid molecules in a sample of polynucleotides based on epigenetic state, comprising:
-
a. adding a set of epigenetic-control nucleic acid molecules to the nucleic acid molecules in the sample of polynucleotides, thereby producing a spiked-in sample; b. partitioning nucleic acid molecules of at least a subset of the spiked-in sample into a plurality of partitioned sets; c. enriching at least a subset of molecules from the plurality of partitioned sets to generate a set of enriched molecules, wherein the set of enriched molecules comprises a group of epigenetic-control nucleic acid molecules and a group of nucleic acid molecules from the sample of polynucleotides; d. sequencing at least a subset of the set of enriched molecules to produce a set of sequencing reads; e. analyzing at least a subset of the set of sequencing reads to generate one or more epigenetic partition scores of the epigenetic-control nucleic acid molecules; and f. comparing the one or more epigenetic partition scores with one or more epigenetic partition cut-offs. - View Dependent Claims (42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 54, 55, 57, 58, 59, 61, 62, 63, 65, 66, 67, 68, 70, 72, 73, 76)
