[BioC] gff files: how to tell if right-open interval convention used?

[karlerhard at berkeley.edu]

Hi all,

I'm a grad student at UC Berkeley, I'm new to the list, as well as to R
programs in general, so I hope you'll forgive my simplistic questions.

I'm working with the girafe package to generate counts table which can be
input into edgeR.  I've noticed that the readGff3 function is sensitive to
whether the gff file being read uses this "right-open interval convention"
or not.  I'm just not sure how to tell if the gff file I am using follows
this convention.  Is there a simple way to find out?

Any help on this would be greatly appreciated.

best,

karl
