Dear Caroline and Nike,

Import your data to EEGLAB. You may or may not have your digitized channel
locations. If you do, you should import it. If you don't, I expect you
still have channel labels, and I also expect that the labels are Fz, Cz,
Pz... or other popular things (like geodesic sensor system etc). If your
labels are Fz, Cz, Pz... then EEGLAB can retrieve their canonical positions
on MNI head model automatically. After you load the channel location info,
you process your data and you can show scalp topography of your desired
condition and latency.
