### Arguments

`GR.annotation` | the genomic regions of annotation data. By default, it is 'NA' to disable this option. Pre-built genomic annotation data are detailed in the section 'Note'. Alternatively, the user can also directly provide a customised GR object (or a list of GR objects or a GRL object)
`verbose` | logical to indicate whether the messages will be displayed in the screen. By default, it sets to false for no display
`RData.location` | the characters to tell the location of built-in RData files. See `xRDataLoader` for details
