[Eeglablist] difference maps

Plotting difference maps might be possible from command line (Arno would
answer that better). But computing statistics on scalp maps is not in
EEGLAB as far as I know. You might want to check out FIELDTRIP
(http://www2.ru.nl/fcdonders/fieldtrip/) and the latest version of SPM
(SPM5 betha at http://www.fil.ion.ucl.ac.uk/spm/ ) for possible
solutions.

Subject: [Eeglablist] difference maps
 
Dear list members,
 
I'm comparing ERPs in two conditions and I'd like to show the difference
between this conditions plotted as maps, not only in the ERP waveforms.
Is it possible to compute and show the T-maps of significant differences
between conditions? Or just plot the difference map for a specific time
range? 
 
Would be very thankful for any help.
 
Best Regards,
Olga.
