cohrefchannel

[Gregor Volberg]

Hi Marco,

to be able to specify a reference channel, it seems to be necessary to have
a field named xy.cohspctrm. You might simply copy the plvspctrm into a new
field,

plv_data.cohsprctm = plv_data.plcspctrm 

and then multiplot with the option 

cfg.cohrefchannel    = 'Cz';

The plots should then look different for different reference channels.

Hope this helps?,
Gregor
