It outputs measures of average alleles +shared and measures of variability for each pair of subjects and creates an interactive image where each pair is +plotted in this mean/variance space. It is based on the GRR windows application available at +http://www.sph.umich.edu/csg/abecasis/GRR/ + +The plot is interactive - you can unselect one of the relationships in the legend to remove all those points +from the plot for example. Details of outlier pairs will pop up when the pointer is over them. e found by moving your pointer +over them. This relies on a working browser SVG plugin - try getting one installed for your browser if the interactivity is +broken. + +----- + +**Syntax** + +- **Genotype file** is the input pedigree data chosen from available library Plink binary files +- **Title** will be used to name the outputs so make it mnemonic and useful +- **N** is left 0 to use all snps - otherwise you get a random sample - much quicker with little loss of precision > 5000 SNPS + +**Summary** + +Warning - this tool works pairwise so slows down exponentially with sample size. An LD-reduced dataset is +strongly recommended as it will give good resolution with relatively few SNPs. Do not use all million snps from a whole +genome chip - it's overkill - 5k is good, 10k is almost indistinguishable from 100k. + +SNP are sampled randomly from the autosomes - otherwise parent/child pairs will be separated by gender. +This tool will estimate mean pairwise allele shareing among all subjects. Based on the work of Abecasis, it has +been rewritten so it can run with much larger data sets, produces cross platform svg and runs +on a Galaxy server, instead of being MS windows only. Written in is Python, it uses numpy, and the innermost loop +is inline C so it can calculate about 50M SNPpairs/sec on a typical opteron server. + +Setting N to some (fraction) of available markers will speed up calculation - the difference is most painful for +large subject N. The real cost is that every subject must be compared to every other one over all genotypes - +this is an exponential problem on subjects. + +If you don't see the genotype data set you want here, it can be imported using one of the methods available from +the Rgenetics Get Data tool. + +----- + +**Attribution** + +Based on an idea from G. Abecasis implemented as GRR (windows only) at http://www.sph.umich.edu/csg/abecasis/GRR/ + +Ross Lazarus wrote the original pdf writer Galaxy tool version. +John Ziniti added the C and created the slick svg representation. +Copyright Ross Lazarus 2007 +Licensed under the terms of the LGPL as documented http://www.gnu.org/licenses/lgpl.html +</help> +</tool>
