[Eeglablist] ERP output time resolution

[Joon Jang]

Dear EEGlab users,

I am new to EEGlab. We acquired data at 500 Hz. When I plotted ERP wave
forms in 2 conditions with a significance wave using EEGlab, I was able to
obtain a significance value at each time point (in every millisecond
resolution, not every 2ms).

Theoretically, I should not be able to obtain this since it is not the
increments of 2ms.
I was able to find that spline interpolation was used in
"eeg_amplitudearea". Does this apply to the significance wave?

Thank you.

Joon
