ChipDataSet-class: ChipDataSet
Description
The ChipDataSet is a S4 class to store input values, intermediate
calculations and results of ChIP-seq peaks analysis.
Slots
peaksGRanges. ChIP-seq peaks. regionGRanges. Genomic region(s) to extract peaks from. genomicAnnotationData.Frame. Genomic distribution of the peaks
at distinct genomic features (TSSs, exons, introns, intergenic regions). featuresData.Frame. Estimated characteristics (features) of the
peaks. tssOverlapPredictionList. Prediction of the gene associated
peaks. The following elements are reported:
- 'predicted.tssOverlap' - predicted class (yes - gene associated;
no - background) and probability of a ChIP-seq peak being
classified as gene associated.
- 'confusionMatrix' - cross-tabulation of observed and predicted
classes with associated statistics.
- 'logFitSummary' - statistical significance of the predictors
used in the logistic regression.
- 'roc' - results of the receiver operating characteristic
analysis.
strandPredictionList. Prediction of the peak strandedness. The
following elements are reported:
- 'predicted.strand' - predicted ChIP-seq peak strand.
- 'probability.cutoff' - probability cutoff for q2.
- 'results.plus' - intermediate calculations for the forward DNA
strand.
- 'results.minus' - intermediate calculations for the reverse DNA
strand.
