Software
QGene 4.0, for QTL analysis and data exploration.tAUDPC, for computing and viewing truncated AUDPC plots. Sample tAUDPC data file
QRMap, for drawing unrolled restriction maps of circular genomes. Sample QRMap data file
MatLink, MATLAB program for computing linkage in exotic line-cross mating designs
PrimerDB, a database and WWW interface for managing PCR primers, especially for mapped wheat ESTs. Details
Population Phenology and Weather Viewer, an experimental tool for visualizing phenology and environment variables in multi-environment trials
I have extended CarthaGène, an open-source multipoint linkage-mapping software package developed by Thomas Schiex and colleagues, to handle mating designs consisting of arbitrary series of backcrossing, selfing, and random-intercrossing steps. A 32-bit Linux but not yet a Windows version is available as v1.1 on the CarthaGène site. We can supply a 64-bit version.
