Peak Annotation Hypergeometric Enrichment in Marker Peaks.

This function will perform hypergeometric enrichment of a given peak annotation within the defined marker peaks.

peakAnnoEnrichment(
  seMarker = NULL,
  ArchRProj = NULL,
  peakAnnotation = NULL,
  matches = NULL,
  cutOff = "FDR <= 0.1 & Log2FC >= 0.5",
  background = "all",
  logFile = createLogFile("peakAnnoEnrichment")
)

Arguments

seMarker

A SummarizedExperiment object returned by markerFeatures().

ArchRProj

An ArchRProject object.

peakAnnotation

A peakAnnotation object in the provided ArchRProject to be used for hypergeometric testing.

matches

A custom peakAnnotation matches object used as input for the hypergeometric test. See motifmatchr::matchmotifs() for additional information.

cutOff

A valid-syntax logical statement that defines which marker features from seMarker to use. cutoff can contain any of the assayNames from seMarker.

background

A string that indicates whether to use a background set of matched peaks to compare against ("bgdPeaks") or all peaks ("all").

logFile

The path to a file to be used for logging ArchR output.
