Counting of regions within a segment

[DrD2009]

Hello everyone. I have a scripting/coding question.

I'm trying to run an analysis to find the number of regions found within a particular segment length throughout a chromosome.

For instance:


Chr1-



In this case the segments are broken into 50 basepair lengths along the entire chromosome, but a way to vary that length would be desired. The starting file would most likely compose of either a .BED or .GFF

The desired output of such an analysis for the example above would be as such:

[Segment] \t [Count_of_regions]
1-49		4
50-99		5	
100-149		4
150-199		6

Any help with this would be greatly appreciated.


Thanks.
