[Eeglablist] Is EEGLAB able to calculate t-score between two conditions?

[Stephen Politzer-Ahles]

Hello Jianrong,

The Sum/Compare ERPs dialog (underneath the Plot menu; or pop_comperp()
from the command line) can do this with waveforms. It plots waveforms of
all the channels on a scalp array, and marks the times on each channel
where *t* is significant.

I don't know if EEGLAB has a tool to show t-statistics on a topoplot. But
you can do this fairly easily by using basic MATLAB commands on the ERPs
(from EEG.data), to get a CHANNELSxSAMPLES array of t-statistics, and then
give those t statistics (rather than ERP data) to the topoplot() command.

Best,
Steve Politzer-Ahles
