RAIDS: Robust Ancestry Inference using Data Synthesis

This package implements specialized algorithms that enable genetic ancestry inference from various cancer sequences sources (RNA, Exome and Whole-Genome sequences). This package also implements a simulation algorithm that generates synthetic cancer-derived data. This code and analysis pipeline was designed and developed for the following publication: Belleau, P et al. Genetic Ancestry Inference from Cancer-Derived Molecular Data across Genomic and Transcriptomic Platforms. Cancer Res 1 January 2023; 83 (1): 49–58.

Datasets:
  • demoKnownSuperPop1KG - The known super population ancestry of the demo 1KG reference profiles.
  • demoPCA1KG - The PCA results of the demo 1KG reference dataset for demonstration purpose. Beware that the PCA has been run on a very small subset of the 1KG reference dataset and should not be used to call ancestry inference on a real profile.
  • demoPCASyntheticProfiles - The PCA result of demo synthetic profiles projected on the demo subset 1KG reference PCA.
  • demoPedigreeEx1 - The pedigree information about a demo profile called 'ex1'.
  • matKNNSynthetic - A small 'data.frame' containing the inferred ancestry on the synthetic profiles.
  • pedSynthetic - A small 'data.frame' containing the information related to synthetic profiles. The ancestry of the profiles used to generate the synthetic profiles must be present.
  • snpPositionDemo - A small 'data.frame' containing the SNV information.
