[BioPython] Bio.Cluster clarification

[Jimmy Musselwhite]

Hello all
In the documentation it says the "data" argument is "an array containing the
gene expression data". What exactly does that mean? Ideally all I want to do
is send it an array of lists, each containing 3 floats, aka an array of
vectors in 3d space, and have it cluster those. Is that doable?

This may seem like a beginner question but I'm not sure of this
documentation (cluster.pdf).

Thanks!

Or, less likely, if you know of any python lib that can handle this, let me
know!
