# Main : defining utr and intergenic operonic intervalles from a transcripts file following a referencies file 
# 
# Input : 2 gff files to intersect, transcript queries vs referencies
#
# Output : resulting gff file printing to standard output

=head1 NAME

splitTranscriptGff.pl - compare 2 input gff files and define utr and intergenic operonic intervalles by couple of overlapping elements

=head1 SYNOPSIS

% intervallsExtractorGff.pl -i referencies.gff -j transcriptQueries.gff -s strand [-h] 

=head1 DESCRIPTION
This script will intersect 2 gff files and compute distance between 2 successives lines. Take care both of sorting by positions the input files and of that referencies are included in transcriptQueries.

    -i|--input1 fileName   gff input file name: included elements
    -j|--input2 fileName   gff input file name: extended elements
   [-s|--strand] [s|d]	   s for single strand (colinear) or d for double strands (antisense) [default d]
   [-h|--help]             help mode then die                              

=head1 USECASE
Define many fragments for each extended element (transcript): UTR5, gene, UTR3, "inOperon" for intergenomic region between 2 genes
intervallsExtractorGff.pl -i CDSannotations.gff -j RNAseqTranscripts.gff  > UTRsGenesOperonsLists.gff;

=head1 KWON BUGS
No disjonction of overlapping elements of the included elements (-i file).
In usecase, overlapping genes are fused in one long gene.
