Advice needed (^o^)

Hello ....

I am a novice to gcluto.

And recently I had used gcluto to do single pass clustering on thousands of documents(in trectext format) on Windows XP.

I have something which is not clear to me.

why can't I see something like threshold-parameter in gcluto's setting parameters?.

or do I miss something here?

I hope someone who knows about it can be kind enough to enlighten me on this issue. =)

Many thanks in advance.
