ARTP2 is an R package of biological pathway analysis or pathway meta-analysis for genome-wide association studies (GWAS). It also provides tools for gene-level test as a special case. ARTP2 is an enhanced version of two previously released packages ARTP and AdaJoint. The current version is 0.9.20.
Features
- Association test on user-defined genes or pathways
- No need to assume independence between genes in a pathway (genes can be closeby or overlapped)
- Accepting individual-level genetic data or SNP-level summary statistics from one or multiple GWAS
- Supporting continuous or binary outcome (case-control studies)
- Comprehensive data pre-processing options
- Automatic allele validation and matching in processing inputs from summary data
- Inflation factor adjustment
- Toolkit for SNP-level meta-analysis
- Parallelization under Linux-like OS using OpenMP
