how to remove event markers in BDF file
how to remove event markers in BDF file
My BDF files show several event markers (around 100 multi-colored vertical lines in a span of just 1 second with numeric labels) for the whole duration of eeg data. I don't know what setting has changed that is causing this. Any help regarding how to revert back so that I don't see any of these event markers will be truly appreciated. I am using KT88-1016 to record and export eeg data into BDF file and EEGLAB to plot the scrollable eeg from the BDF file.

Re: how to remove event markers in BDF file
The false triggers are probably caused because you have a nothing (or a sensor other then a manual Response Switch) connected to the ERGO input (floating input), while the CFG is set for overwriting triggers 9 and 10 from signals from manual Response Switches (connected to the ERGO).
Edit the CFG with Notepad. The 5th line in the CFG is now probably:
RespSwitch=1 //0: standard ergo, 1: ergo 1 & 2 coupled to trigger 9 & 10, 2: switch input coupled to trigger 9 & 10
Change this to:
RespSwitch=0
Do not change anything else in the CFG
Use different CFGs for operation with, or without connected Response Switches.
