[Eeglablist] syncing time 0 ms to stimulus onset

[julia campbell]

Hello all,

I am working with exporting .raw files from EGI Netstation to EEGLab.
Before I export the Netstation files, I high-pass filter the continuous file and then ‘segment’ the data to create epochs.
My stimuli have timing offsets that are programmed into the segmentation process in Netstation.
As a result, when I examine the data in EEGLab, I have a stimulus marked as occurring before 0 ms latency.
How can I mark 0 ms as the same point that the stimulus occurs?

Thank you for your help!
