[BioC] FlowCore covariance matrix for ellipsoidGate

[Aric Gregson]

Hello,

I do not understand how to define an ellipsoidGate in flowViz very
well. I think my main problem is that I do not understand what the
covariance matrix should consist of. I am attempting to use an
ellipsoidGate to pick a middle population in a FSC.A vs. FSC.W plot. 

Any pointers on how to figure out an appropriate covariance matrix?

Thanks.
