QTL Reaper Description

QTL Reaper is software for rapidly scanning microarray expression data for QTLs. QTL Reaper is software, written in C and compiled as a Python module, for rapidly scanning microarray expression data for QTLs. It is essentially the batch-oriented version of WebQTL. It requires, as input, expression data from members of a set of recombinant inbred lines and genotype information for the same lines. It searches for an association between each expression trait and all genotypes and evaluates that association by a permutation test. For the permutation test, it performs only as many permutations as are necessary to define the empirical P-value to a reasonable precision. It also performs bootstrap resampling to estimate the confidence region for the location of a putative QTL. Requirements:· Python· blas library· lapack libraryINSTALLATION:First gunzip and untar the package file. Enter the qtlreaper directoryTo compile qtlreaper module, execute: python setup.py build you may also modify the setup.py script if your system doesn't have blas and lapack library installed and want to use the ones included in this package.To install qtlreaper module, execute: python setup.py install What's New in This Release:· Increase maximum locus in one single chromosome from 200 to 500· New code to calculate missing markers
