[Bioperl-l] SeqFeatureI.pm: get all starts and ends from 'join'

[Jan Aerts]

Hi all,

I'm trying to extract all exon boundaries from a genbank file. The
relevant feature of the file looks like this:
mRNA   complement(join(1..238,718..763,1552..1677,1925..2004))

Using $feat->start and $feat->end, I can get the numbers 1 and 2004, but
I can't seem to get hold of the other exon/intron boundaries? Can anyone
tell me how to get to these numbers?

Thanks,
Jan Aerts
