[Eeglablist] ICA and dipole question

[Makoto Miyakoshi]

Dear Sara,

I have filed probably the same issue and solution here (Bugzilla 1410). If
you want to try this solution, open type as follows in the matlab command
window.

edit dipole_fit
(find 'maxiter' and change the default value to be 10 times larger)

https://sccn.ucsd.edu/bugzilla/show_bug.cgi?id=1410

dipole_fit() 'maxiter' default value could be too small

When I ran dipole fitting with my 32ch EEG datasets,several NaNs were
generated for r.v.(IC1, IC2,... especially when they show two-dipole
maps) which is pretty inconvenient. I increased 'maxiter' to x10 of
the default and it worked. Maybe you want to consider to increase it
since computational power is so cheap today?
