[BiO BB] redundant data

[Pankaj]

hi everybody,
i have a set for 200 sequences where the sequence similarity varies
between 28-90%. i want to select a representative set from this bigger
set so that i pick up sequences which are representative of the whole
set. ie from this bigger set i want to remove the sequences that are
very similar and represent them by just a single sequence. ie i want
to have a non redundant set. can anyone please tell how
thanx in advance
