seqOpen: Open a SeqArray GDS File
In SeqArray: Data management of large-scale whole-genome sequence variant calls

Description Usage Arguments Details Value Author(s) See Also Examples

Opens a SeqArray GDS file.

1	seqOpen(gds.fn, readonly=TRUE, allow.duplicate=FALSE)

`gds.fn`	the file name
`readonly`	whether read-only or not
`allow.duplicate`	if `TRUE`, it is allowed to open a GDS file with read-only mode when it has been opened in the same R session

It is strongly suggested to call seqOpen instead of openfn.gds, since seqOpen will perform internal checking for data integrality.

Return an object of class SeqVarGDSClass inherited from gds.class.
