UNLABELLED: Of many statistical methods developed to date for quantitative trait locus (QTL) analysis, only a limited subset are available in public software allowing their exploration, comparison and practical application by researchers. We have developed QGene 4.0, a plug-in platform that allows execution and comparison of a variety of modern QTL-mapping methods and supports third-party addition of new ones. The software accommodates line-cross mating designs consisting of any arbitrary sequence of selfing, backcrossing, intercrossing and haploid-doubling steps that includes map, population, and trait simulators; and is scriptable. AVAILABILITY: Software and documentation are available at http://coding.plantpath.ksu.edu/qgene. Source code is available on request.

Numerous researchers have reported success in reasoning about properties of small programs using finite-state verification techniques. We believe, as do most researchers in this area, that in order to scale those initial successes to realistic programs, aggressive abstraction of program data will be necessary. Furthermore, we believe that to make abstraction-based verification usable by non-experts significant tool support will be required. In this paper we describe how several different program analysis and transformation techniques are integrated into the Bandera toolset to provide facilities for abstracting Java programs to produce compact, finite-state models that are amenable to verification for example via model checking. We illustrate the application of Bandera's abstraction facilities to analyze a realistic multi-threaded Java program.
