Estimate and Account for Tumor Purity in Cancer Methylation Data Analysis
Print abbreviations of cancer types with known iDMCs.
Estimate the tumor purity for 450K methylation data
Tumor sample clustering from Infinium 450k array data
Differentially Methylation Calling accounting for tumor purity
Purify tumor methylomes caused by normal cell contamination.
The proportion of cancer cells in solid tumor sample, known as the tumor purity, has adverse impact on a variety of data analyses if not properly accounted for. We develop 'InfiniumPurify', which is a comprehensive R package for estimating and accounting for tumor purity based on DNA methylation Infinium 450k array data. 'InfiniumPurify' provides functionalities for tumor purity estimation. In addition, it can perform differential methylation detection and tumor sample clustering with the consideration of tumor purities.
