GreyList
objectThough a BSgenome
object (or a karyotype file, or a
GRanges
) is
supplied when the
GreyList
object is created, it is conceivable that
the user might want to replace it. This method allows that.
setRegions(obj, regions, tileSize=1024)
obj |
A |
regions |
A |
tileSize |
The size in nucleotides of each tile. Overlapping tiles will be generated, spaced at 1/2 the width of the tiles. |
Returns the GreyList
object with a new
tiling.
