easyTENET	Run the step 1 through step 6 functions with default arguments
humanTranscriptionFactorDb	Human transcription factor database
humanTranscriptionFactorList	Human transcription factor list
step1MakeExternalDatasets	Create a GRanges object representing putative regulatory element regions, based on the data sources selected for inclusion, to be used in later TENET steps
step2GetDifferentiallyMethylatedSites	Identify differentially methylated RE DNA methylation sites
step3GetAnalysisZScores	Calculate Z-scores comparing the mean expression of each gene in the case samples that are hyper- and/or hypomethylated for each RE DNA methylation site identified in step 2
step4SelectMostSignificantLinksPerDNAMethylationSite	Select the most significant RE DNA methylation site-gene links to each RE DNA methylation site
step5OptimizeLinks	Find final RE DNA methylation site-gene links using various optimization metrics
step6DNAMethylationSitesPerGeneTabulation	Tabulate the total number of RE DNA methylation sites linked to each gene
step7ExpressionVsDNAMethylationScatterplots	Create scatterplots displaying the expression of the top genes and the methylation levels of each of their linked RE DNA methylation sites, optionally incorporating copy number variation, somatic mutation, and purity data
step7LinkedDNAMethylationSiteCountHistograms	Create histograms displaying the number of total genes and transcription factor genes linked to a given number of RE DNA methylation sites
step7LinkedDNAMethylationSitesMotifSearching	Search for transcription factor motifs in the vicinity of DNA methylation sites and/or within custom regions defined by the user
step7SelectedDNAMethylationSitesCaseVsControlBoxplots	Generate boxplots or violin plots comparing the methylation level of the specified RE DNA methylation sites in case and control samples
step7StatesForLinks	Identify which of the case samples harbor each of the identified regulatory element DNA methylation site-gene links
step7TopGenesCaseVsControlExpressionBoxplots	Generate boxplots or violin plots comparing the expression level of the top genes and transcription factors in case and control samples
step7TopGenesCircosPlots	Generate Circos plots displaying the links between the top identified genes and each of the RE DNA methylation sites linked to them
step7TopGenesDNAMethylationHeatmaps	Generate heatmaps displaying the methylation level of all RE DNA methylation sites linked to the top genes and transcription factors, along with the expression of those genes in the column headers, in the case samples within the supplied MultiAssayExperiment object
step7TopGenesExpressionCorrelationHeatmaps	Generate mirrored heatmaps displaying the correlation of the expression values of the top genes and TFs
step7TopGenesOverlappingLinkedDNAMethylationSitesHeatmaps	Generate binary heatmaps displaying which of the top genes and transcription factors share links with each of the unique regulatory element DNA methylation sites linked to at least one top gene/TF
step7TopGenesSurvival	Perform Kaplan-Meier and Cox regression analyses to assess the association of patient survival with the expression of top genes and transcription factors and methylation of their linked RE DNA methylation sites
step7TopGenesTADTables	Create tables using user-supplied topologically associating domain (TAD) information which identify the TADs containing each RE DNA methylation site linked to the top genes and transcription factors, as well as other genes in the same TAD as potential downstream targets
step7TopGenesUCSCBedFiles	Create BED-formatted interact files which can be loaded on the UCSC Genome Browser to display links between top genes and transcription factors and their linked RE DNA methylation sites
step7TopGenesUserPeakOverlap	Identify if RE DNA methylation sites linked to top genes and transcription factors are located within a specific distance of specified genomic regions
TCGADownloader	Download TCGA gene expression, DNA methylation, and clinical datasets and compile them into a MultiAssayExperiment object
TENETCacheAllData	Cache all online datasets required by TENET examples and optional features
