1. A method of obtaining sequence information from one or more targeted portions of a genomic sample, the method comprising:
- (a) providing a plurality of fragments from the genomic sample in discrete partitions, wherein each of the fragments further comprises a barcode, and wherein at least first and second fragments within 10 kb of each other in a contiguous sequence of the genomic sample comprise a common barcode, and wherein the discrete partitions are flowable within fluid streams;
(b) applying a library of probes directed to the one or more targeted portions of the genomic sample to the plurality of fragments;
(c) conducting a first sequencing reaction to identify sequences of the plurality of fragments that hybridized to the library of probes, thereby obtaining sequence information from the one or more targeted portions of the genomic sample;
(d) conducting a second sequencing reaction to identify sequences of fragments from the discrete partitions that did not hybridize to the library of probes.

Abstract
The present invention is directed to methods, compositions and systems for capturing and analyzing sequence information contained in targeted regions of a genome. Such targeted regions may include exomes, partial exomes, introns, combinations of exonic and intronic regions, genes, panels of genes, and any other subsets of a whole genome that may be of interest.
