The FEATURES program of the XYLEM package can do what you
want. FEATURES can extract sequences from GenBank entries
using any Feature Key (eg. intron, mRNA, CDS, rRNA, exon....).
Even features that are derived from many entries can be
correctly assembled in an automated fashion. Perhaps importantly,
FEATURES can work on large groups of GenBank entries at
a time. So if you have 200 GenBank entries and you want all the
introns or exons extracted, that can be done in one step.
