## Reset Variant ID in SeqArray GDS Files

### Description

Resets the variant IDs in multiple SeqArray GDS files.

### Usage

    seqResetVariantID(gds.fn, set=NULL, digest=TRUE, optimize=TRUE, verbose=TRUE)

### Arguments

`gds.fn` | a list of file names of multiple GDS files
`set` | NULL or a logical vector; NULL for resetting all files, or TRUE for resetting variant.id for that GDS file
`digest` | a logical value, if TRUE, add a md5 hash code
`optimize` | if `TRUE`, optimize the access efficiency by calling `cleanup.gds`
`verbose` | if `TRUE`, show information

### Details

The variant IDs will be replaced by the numbers in sequential order and adjacent to each file. The variant ID starts from 1 in the first GDS file.

### Value

None.

### Examples

    fn <- seqExampleFileName("gds")

    file.copy(fn, "tmp1.gds", overwrite=TRUE)
    file.copy(fn, "tmp2.gds", overwrite=TRUE)

    gds.fn <- c("tmp1.gds", "tmp2.gds")
    seqResetVariantID(gds.fn)

    f <- seqOpen("tmp1.gds")
    head(seqGetData(f, "variant.id"))
    seqClose(f)

    f <- seqOpen("tmp2.gds")
    head(seqGetData(f, "variant.id"))
    seqClose(f)

    # delete the temporary files
    unlink(gds.fn, force=TRUE)
