Data for TCGA Workflow

Description

This experimental data package has the data necessary to follow the TCGA Workflow: Analyze cancer genomics and epigenomics data using Bioconductor packages. It contains the following files:

  • met20SamplesGBMLGGchr9: DNA methylation matrix from Infinium HumanMethylation450 platform for 10 LGG (Lower grade glioma) and 10 GBM (Glioblastoma multiforme). It has only probes in chromossome 9 in order to make the example of the workflow faster

  • elmerExample: Contains a DNA methylation matrix (only probes in chromossome 9) and a gene expression matrix for 10 LGG (Lower grade glioma) and 10 GBM (Glioblastoma multiforme) in the required format for to execute the R/Bioconductor ELMER package analysis and a vector identifying which sample belongs to each tumor type.

  • biogrid: biogrid information

  • maf_lgg_gbm: Mutation annotation files for LGG (Lower grade glioma) and GBM (Glioblastoma multiforme) samples merged into a single matrix. The GDC Somatic Mutation Calling Workflow mutect2 was used to create this MAF files.

  • histoneMarks: histone marks specific for brain tissue using from Roadmap database.

  • genes_GR: A GRanges Object and a dataframe with gene information (hg19) downloaded from ENSEMBLE database using biomart via TCGAbiolinks

  • TCGA_GBM_Transcriptome_20_samples: a matrix with raw expression signal for expression of a gene for 20 GBM (Glioblastoma multiforme) samples

  • TCGA_LGG_Transcriptome_20_samples: a matrix with raw expression signal for expression of a gene for 20 LGG (low grade glioma) samples

For more information how to create these objects please read the vignette of this package with the follwing command: browseVignettes("TCGAWorkflowData")
