Incorrect epoch time when importing database

I am working to import trial data from EEG (.mff raw file type). I have the epoch time set as [-200 to 4000 ms] but it's cutting off all trials at 1 second regardless of how I adjust this setting. I've never seen this issue before, so any help you can offer would be greatly appreciated!

Edit. Improved screenshot

Hi @tmcentanni,

The behaviour you see is related to the type of events. Your events are extended (thus the [ext] in their name). As such when importing, the epoch times (-200-4000ms) are ignored. The duration of the events is used instead (which I assume is 1 s).

The solution is in a previous post

Ah yes that makes sense - thank you!
