**What it does**
  
Divides input genomic regions into regions of size N bp which overlap each other by N/2 bp.  If genome-wide prediction is desired, a single BED file listing the total length of each chromosome should be provided as input.x

**Parameters**
  
Size of Genome Fragments: Size of regions into which genome will be split.
  
Size of Overlap: Size of overlap between genomic regions.

BED File of Regions for Prediction: Regions to be split according to above criteria.

----
  
**Example**
  
Given a BED file, tool will output BED file of regions of length N, which overlap by N/2 bp::
  
    chr1	0	1000
    chr1	500	1500
    chr1	1000	2000
    chr1	1500	2500
