incorrect junction and intron coordinates

In the flux capacitor, the junction goes from the last base of an exon to the first base of another exon. It should start 1 bp after the end of an exon and end 1 bp before the start of another exon.
for example:
exon1 = 3-10
exon2= 17-24
-> junction = 11-16
and not 10-17 as it is now.

This problem also affects the intron rows. In general junction and intron rows have 2 more bp than what they should have.
