[Bioperl-l] Extract features from GFF

[Hang]

Hello,

I have a list of about 100,000 short genomic regions with paired start and end
coordinations on reference fly genome (R5.3). I also have GFF files from the
same genome release. I wonder how I can extract all overlapping features from
these regions.

For example:

region A is on chromosome 2L between 123,456 bp to 123,489 bp. What code should
I use to extract feature, like gene, CDS etc., that overlaps with this region?

Thank you in advance!
