[Eeglablist] Topography of differences

[Paola Melani]

Dear everyone,

I work on ERP study that i process with EEGLAB. I would like to do a topography difference of a window of interest as we can see in some scientific papers.
With the Study function, I can do one topography for a window of interest of 0 to 200 for example for each experimental condition, while I would like to do one topography each 50 ms (0ms; 50ms, 100ms and 200ms) that show the activation difference between a condition 1 and a condition 2.
I’m looking for on internet and on eeglab tutorials’, but I do not find how can I do this, so someone know or have the script to do this topographies differences ?

Thank you very much for your help.
