GenePool

About GenePool

GenePool is a software package that provides analysis tools for the detection of shifts in relative allele frequency between pooled genomic DNA from cases and controls using SNP-based genotyping microarrays. Funding of GenePool is made possible through a National Institutes of Health ENDGAME grant (U01-HL086528-421-43401).

The GenePool system consists of two executable programs, gpextract and gpanalyze and one perl script gpcommand The first GenePool script gpextract uses the Affymetrix Fusion SDK library to extract intensity values from Affymetrix CEL files and write them to a customized, more compact binary file format. The new files have the same name as the original CEL file but with the string .gpb appended to each filename. gpanalyze takes the intensity values from the .gpb files and uses a variety of distance measures to assign a probability score to each SNP where the score indicates how unlikely is the observed difference in allele frequency between the hybridizations for the two DNA pools.

The primary documentation for GenePool is the man pages that accompany the distributions. The genepool man page is the primary project documentation and should be used as the jumping-off point for anyone looking for information about how to use GenePool. It contains installation instructions for the binary and source code distributions of GenePool as well as Known Issues and a To Do section that outlines major areas of development effort.

Release Numbers

GenePool will use the odd-even system to denote development and stable releases. Stable releases will be made periodically and will end in an even digit, for example 0.12, 0.16.2, 1.06. The current development code will also be periodically copied to the download site and will end in an odd number, for example 0.13, 0.17, 1.07.
