[Eeglablist] help: source reconstruction with time course

Hello. Im trying to perform a source reconstruction from a 10-20 system of
19 channel locations, after I perform ICA, I go for dipole fitting using
dipfit, and I obtain exactly the same number of dipoles than the number of
channels, and I only get  the positions at a single time moment.

My question is: How can I  get the source reconstruction of the dipoles in
the entire timecourse of the signals of the channels, and why I am obtaining
the same number of sources: isn't it supposed to be greater the number of
sources than the number of scalp measures?

Another thing is: if I have the radius of the spherical head model, how can
I use this volume and conductance configurations rather than those that
already exist in eeglab?

thank you for all your replies
