Quantitative trait tool• Selects genes which are univariately correlated witha quantitative trait such as age or time point.• Controls number and proportion of falsediscoveries in entire list: uses a multivariatepermutation test which takes advantage of thecorrelation among genes.• Produces a gene list which can be used for furtheranalysis.• Produces chromosomal distribution and GOanalysis if genes have already been annotated usingthe SOURCE database.98
Survival analysis tools• Find Genes Correlated with Survival tool, selects geneswhich are univariately correlated with survival• Controls number and proportion of false discoveries inentire list: uses a multivariate permutation test which takesadvantage of the correlation among genes• Produces a gene list which can be used for further analysis.• Produces chromosomal distribution and GO analysis ifgenes have already been annotated using the SOURCEdatabase.99
