A list of pathways and 11 datasets consisting gene expressions and phenotypes as the benchmark for Gene Set Analysis. Most of this information was used to validate Differential Rank Conservation (DIRAC) in the first place. In addition the data in the Eddy et al. (2010) paper, we also provide two datasets.

Description

The GSBenchMark package contains data for testing gene set analysis with two phenotypes. Specially, the user can use the datasets used for validating Differential Rank Conservation (DIRAC) (Eddy et al. 2010). This datasets are used in the package GSReg which implements DIRAC and a more efficient alternative called GSVReg.

GSBenchMark package features

The dataset are included:

leukemia_GSEA marfan_GDS2960 melanoma_GDS2735 parkinsons_GDS2519 prostate_GDS2545_m_nf prostate_GDS2545_m_p prostate_GDS2545_p_nf sarcoma_data squamous_GDS2520 breast_GDS807 bipolar_GDS2190 The phenotypes has also been provided and the pathways. For more details, please see the individual help of each dataset as well as (Eddy et al. 2010).
