A method for assembling nucleic acid sequence fragments is disclosed. The fragments are assembled using information about their relative position inferred by comparison of the fragments against a known sequence of a related nucleic acid (FIG. 3). Additionally, the method localizes fragments to bacterial artificial chromosomes (FIG. 1) and determines relative position of bacterial artificial chromosomes using sequence comparison information (FIG. 6). The method utilizes the information about relative orientation, mutual distance, fragment localization to bacterial artificial chromosomes, and relative position of bacterial artificial chromosomes to constrain the assembly process (FIG. 5), thus resulting in a more accurate assembly requiring fewer sequencing reactions.

A dataflow instruction set architecture and execution model, referred to as WaveScalar, which is designed for scalable, low-complexity/high-performance processors, while efficiently providing traditional memory semantics through a mechanism called wave-ordered memory. Wave-ordered memory enables “real-world” programs, written in any language, to be run on the WaveScalar architecture, as well as any out-of-order execution unit. Because it is software-controlled, wave-ordered memory can be disabled to obtain greater parallelism. Wavescalar also includes a software-controlled tag management system.

Chromatograms and mass spectra produced by an LC/MS system are analyzed by creating a two-dimensional data matrix of the spectral and chromatographic data. The two-dimensional matrix can be created by placing the spectra generated by the mass spectrometer portion of the LC/MS system in successive columns of the data matrix. In this way, the rows of the data matrix correspond to chromatographic data and the columns of the data matrix correspond to the spectra. A two-dimensional filter is specified and applied to the data matrix to enhance the ability of the system to detect peaks associated with ions. The two-dimensional filter is specified according to desired criteria. Rank-1 and rank-2 filters can be specified to improve computational efficiency. One method of applying the two-dimensional filter is through convolution of the data matrix with the two-dimensional filter to produce an output data matrix. Peaks corresponding to detected ions are identified in the output data matrix. Parameters of the peaks are determined and stored for later processing including quantitation, or simplification of chromatograms or spectra by, for example, identifying peaks associating with ions having retention times falling within a specified retention time window or having mass-to charge ratios falling within a specified mass-to-charge ratio window.
