[Eeglablist] syncing time 0 ms to stimulus onset

[Nike gnanateja]

Dear Dr. Campbell,

Doesn't setting the trigger offset in the segmentation process in
Netstation solve your problem. You just record the latency offsets using
the AV device testing unit and check for the offsets, and plug them into
the trigger offset field in the segmentation process. But having said that,
I think you must have already tried that out.

I too am still awaiting a reply from eeglab about setting trigger offsets
during the epoching process.


regards,
Nike
