## STATegRa data

### Description

mRNA data (`Block1`), miRNA data (`Block2`) and the design matrix (`ed`), from `STATegRa_S1`, provides selected data downloaded from https://tcga-data.nci.nih.gov/docs/publications/gbm_exp/. The mapping between miRNA and mRNA (`mapdata`, available in `STATegRa_S2`) contains, as a processed matrix, selected information available from TargetScan; we selected the set of miRNA target predictions for humans for those miRNA-mRNA pairs where both miRNA and mRNA were in `Block1` and `Block2` respectively.

The PCA version of the data (`Block1.PCA`, `Block2.PCA`, `ed.PCA`; available in `STATegRa_S3`), provides a similar data-set to `Block1`, `Block2` and `ed` data; however in this case the data has been processed in order to provide a pedagogic example of OmicsPCA. Results obtained from OmicsPCA (`omicsCompAnalysis`) with the existing data should not be taken as clinically valid.

### Format

Two matrices with mRNA and miRNA expression data, a design matrix that describes both and a mapping between miRNA and genes.
