[Eeglablist] deleting time segments in continuous data based on event codes

[fredrik heinat]

Dear all,

I have data from a linguistic RSVP-experiment where participants have 
read sentences. Every sentence starts with a fixation cross with event 
code 1 and the end of the final word has eventcode 99, and there are no 
other event codes between sentences. The sentences are not of equal 
length and the time between sentences varies too since the participants 
decide themselves when to start the next sentence. In preparation for 
ICA it would be really nice with a script that could delete the time 
periods between 99 and 1 (the end of a sentence and the start of the 
next one) since the periods between sentences contain a lot of EMG and 
eye movements unrelatede to the study. I've not been able to find 
anything  on the list, or elsewhere, that can remove time periods in 
continuous data which is not based on certain fixed time periods between 
events. I've tried the script: 
https://urldefense.com/v3/__https://github.com/lucklab/erplab/blob/master/pop_functions/pop_erplabDeleteTimeSegments.m__;!!Mih3wA!Cl_njzFlp18yt-kI7_EPMV8MKxkoPuOhFb6jrVWR4mqxs0ubb6GwRrSioUtcMSVTkizps3iZGuYt_aNRAZNjgw2S8HoZdw$  
but I can't get it to work. The problem is that the between sentence 
interval can be both longer and shorter than the one between any 
critical events in the sentences so a specific time intervall can't be 
specified. I'm not used to Matlab programming and I'd appreciate any 
help I can get.

Best,
Fredrik
