Perform overlap queries between reads and genome by sliding windows Count reads over sliding windows.

tileCount2(reads, fragment.length = 100, windowSize = 50000,
  restrict = paste0("chr", c(1:19, "X", "Y")), step = 1000,
  filter = 0, pe = "both")

`reads`	An object that represents the names and path of the bam files to be counted. If reads are more than 1 bam files, it should be a vector of character with full path. This function now works for paired end reads
`fragment.length`	integer(1). An integer scalar or a list of two integer scalars/vectors, containing the average length(s) of the sequenced fragments in each libary.
`windowSize`	numeric(1) or integer(1). Size of the windows.
`restrict`	restrict to a set of chromosomes, default to mouse chromosomes.
`step`	numeric(1) or integer(1). Step of generating silding windows.
`filter`	default to 0 without filtering. An integer scalar for the minimum count sum across libraries for each window
`pe`	a character string indicating whether paired-end data is present; set to "none", "both", "first" or "second"

A RangedSummarizedExperiment object with chromosome-level depth The assays slot holds the counts, rowRanges holds the annotation from the sliding widows of genome. metadata contains lib.size.chrom for holding chromosome-level sequence depth
