[Eeglablist] Scaling issue when copying ica weights/sphere.

Hello experts:

I cleaned and ran ica on an epoched dataset. The components looked good all around.  

1. When I went to copy the ica weight and sphere matrices to the same dataset that was continuous, the components activation is now super high.  On the order of 50x greater, and it looks poorly.  

2. However , when I copy the weight matrices from an epoched to another epoched dataset, it looks normal.  

Any thoughts on where I want wrong?  The scaling is wrong somewhere, as clearly people copy ica weights from epoched to continuous data normally.
