## prepare data for permutation test

### Description

prepare data for permutation test peakPermTest

### Usage

    preparePool(
      TxDb,
      template,
      bindingDistribution,
      bindingType = c("TSS", "geneEnd"),
      featureType = c("transcript", "exon"),
      seqn = NA
    )

### Arguments

`TxDb` | an object of TxDb
`template` | an object of GRanges
`bindingDistribution` | an object of bindist
`bindingType` | the relevant position to features
`featureType` | feature type, transcript or exon.
`seqn` | seqnames. If given, the pool for permutation will be restrict in the given chromosomes.

### Value

a list with two elements, grs, a list of GRanges. N, the numbers of elements should be drawn from in each GRanges.
