How the extract EEG data according to different epoch limits?
Hey there! Currently I got an EEG data with events like "2", "4", "6","8" which mean the outset of different audio stimui. There are 20 kinds of specific audio stimuli with some similar features for each kind of event/trigger. I have the stimuli matrix generated in each experiment which is in the actual stimulating order. so the specific stimulus for each event could be targeted. In each stimulus, there is 1s silence at the begining and and the end and duration of actual voice is from 1s to 2s. I can use the detectSpeech function to find the outset and end of the voice.
Now I want to extract the EEG data with actual audio stimuli and delete the silence areas, which couldn’t be realized by exracting epochs with specific limits(start and end). could you please tell me how to use script to get the EEG epochs with different length?
