Total_nr_of_region: total number of regions
window_number: window number

### Usage

      checkWindowNumber = TRUE, start0based = TRUE, threads = 10)

### Arguments

`fname` | `character`, file name/path
`uniqIds` | `character vector`, filter stable and keep annotation for these unique ids
`asGRange` | `logical`, boolean, whether to reaturn a GRange object or a data.frame object
`checkWindowNumber` | `logical`, check window number
`start0based` | `logical`, TRUE (default) or FALSE. If TRUE, then the start
