There seems to be a problem with your head model, the forward model has
a nan or an inf.

In general you should not use a local spheres model for realignment.

I have no idea what is causing the problem. Could you send me a matlab
file with an averaged ERF that you want to align and the headmodel
file? Please
use ftp://ftp.fcdonders.nl and put the files in the directory
/pub/inccoming (the directory is one-way-traffic: you cannot see them
there after copying, but I can pich them up from there).
