The GCG program "findpatterns" is the best way to search for defined
patterns of nucleotides or aminoacids.

Alternatively you could screen out simple repeats from the sequence using
something like XNUN (ftp://ibc.wustl.edu/pub/states/xnun.tar.gz) then scan
through your sequence looking for runs of N's.
