[Eeglablist] baseline correction for ERSPs

[Tarik S Bel-Bahar]

Hello Pandelis,

You could just subtract the baseline from each of the epoched files you are
using, for example right after you epoch them.
Load each one in a loop, do the subtraction, and save each baselined file.
Confirm that the baselining has occurred by examining single-subject
single-condition ERPs and erpimage.
Then load all into study and go from there, using only the baselined files.

If you can replicate what seems like a bug, or there is a discrepancy in
the documentation, please take a minute to make a note of it in
eeglab bugzilla.
