R/aSPU is an R package for Genetic association testing methods such as aSPU, aSPUw, aSPUpath, aSPUs, aSPUsPath, GEEaSPU, MTaSPUs, GATES, GATE-Simes, HYST etc.

Summary table

Function Name Data Type Description
aSPU, aSPUw, aSPUr, aSPUd Individual Single trait; gene-based
aSPUs Summary Single trait; gene-based
aSPUpath Individual Single trait; pathway-based
aSPUsPath Summary Single trait; pathway-based
GEEaSPU Individual Multiple traits; single SNP based
MTaSPUs Summary Multiple traits; single SNP based
MTaSPUsSet Summary Multiple traits; gene-based
MTaSPUsSetPath Summary Multiple traits; pathway-based

*Data type indicate the structure of data set. “Individual” for individual level data. “Summary” for summary statistics data (such as Z scores or p-values of each SNP)

Tutorials

Some tutorials for aSPUs, aSPUsPath and MTaSPUsSet are available. - Mapping Snp to Gene - Getting correlation estimate among SNPs from reference panel - R and Perl codes to perform aSPUs and MTaSPUsSet - Pathway data manipulation - Speed comparison using R, awk and Perl - Vignette for aSPUs and aSPUsPath - Vignette for MTaSPUsSet
