Abstract: Methods of preparing organosilane-functionalized regions on a substrate surface and more specifically fabricating patterned functionalized substrates suitable to be optically read, the methods generally comprising employing a vapor deposition process of an organosilane gas onto a lithographically patterned silicon surface followed by removal of the patterning media in a bath of organic solvents and ultrasonic excitation. The inventive methods provide optimized surface density of functional species while avoiding deleterious effects that can occur when lithographically patterned substrates are exposed to various gaseous species during the functionalization process.

Abstract: After DNA fragments are sequenced and mapped to a reference, various hypotheses for the sequences in a variant region can be scored to find which sequence hypotheses are more likely. A hypothesis can include a specific variable fraction for the plurality of alleles that comprise the sequence hypothesis in the region. A likelihood of each hypothesis can be determined using a probability that accounts for the fraction of the alleles specified in the respective sequence hypothesis. Thus, other hypotheses besides standard homozygous and equal heterozygous (i.e., one chromosome with A and one with B in a cell) can be explored by explicitly including the variable fractions of the alleles as a parameter in the optimization. Also, a variant score can be determined for a variant relative to a reference. The variant score can be used to determine a variant calibrated score indicating a likelihood that the variant call is correct.

Abstract: Various short reads can be grouped and identified as coming from a same long DNA fragment (e.g., by using wells with a relatively low-concentration of DNA). A histogram of the genomic coverage of a group of short reads can provide the edges of the corresponding long fragment (pulse). The knowledge of these pulses can provide an ability to determine the haploid genome and to identify structural variations.

Abstract: Data extracted from fluorosphore responses of fluorophore labeled bases in genetic material used in sequencing of unknown fragments from a defined set of for example a model system are converted into a class of block codes that are then employed in a computer-based process to compare and correct preliminary calls of calls of the categorically known genetic material. In a specific embodiment, the Reed-Solomon codes are employed to identify one or more errors as may occur in a finite block of codes. The methodology is also useful to identify elements of a real system containing known elements in the form of a tag. Reed-Solomon sensors may be employed with and in addition to other types of genome sensors.

Abstract: Methods are provided for efficient shotgun sequencing to allow efficient selection and sequencing of nucleic acids of interest contained in a library. The nucleic acids of interest can be defined any time before or after preparation of the library. One example of nucleic acids of interest is missing or low confidence genome sequences resulting from an initial sequencing procedure. Other nucleic acids of interest include subsets of genomic DNA, RNA or cDNAs (exons, genes, gene sets, transciptomes).

Abstract: Sequencing information is used to correlate alleles at certain locations to alleles at other locations. The statistical information from the reads of fragments in a sample can be used to determine the phasing of haplotypes and to correct or confirm based calls at the locations. In one example, a confidence value (strength score) is determined for a particular hypothesis, which can include whether two alleles are on a same haplotype at two particular loci, as well as what the alleles are on another haplotype (e.g. for a diploid organism). The strength can include a positive contribution from data that is consistent with the hypothesis and a negative contribution from data is that inconsistent with the hypothesis, where both values can be used in a formula to determine the strength.
