# Find all regions in data above p-value threshold

### Description

After the ACME calculation, each probe is associated with a p-value of enrichment. However, one often wants the contiguous regions associated with runs of p-values above a given p-value threshold.

### Usage

1 | ```
findRegions(x, thresh = 1e-04)
``` |

### Arguments

`x` |
An |

`thresh` |
The p-value threshold |

### Details

Runs of p-values above the p-value threshold will be reported as one "region". These can be used for downstream analyses, export to browsers, submitted for transcription factor binding enrichment analyses, etc.

### Value

A data frame with these columns:

`Length` |
The length of the region in probes |

`TF` |
Either TRUE or FALSE; TRUE regions represent regions of enrichment while FALSE regions are the regions between the TRUE regions |

`StartInd` |
The starting Index of the region |

`EndInd` |
The ending Index of the region |

`Sample` |
The sample containing the region |

`Chromosome` |
The Chromosome of the region |

`Start` |
The starting basepairof the region |

`End` |
The ending basepair of the region |

`Median` |
The median p-value in the region |

`Mean` |
The mean p-value in the region |
