Hi, everyone,
There was something wrong when I use the fieldtrip function 'definetrial', or exectly 'read_fcdc_event'.
I first got the basic information of my data by using function 'ctf_read', and it returned data which was orgnized as <1800*185*75 double>, that is , there were 75 trials in my data. But when I defined trial by using 'definetrial', (key parameters were configured as follows: cfg.trialdef.eventtype='frontpanel trigger' ; cfg.trialdef.prestim=1; cfg.trialdef.poststim=2; cfg.trialdef.eventvalue=9 %(obtained from 'read_fcdc_event'); ), it showed 88 trials were defined. What's more, I found the trials defined by 'definetrial' were not consecutive.
SO, I want to know what' s wrong with the processing or the fucntion?
Thank you for your answer!
Best wishes.
Li Weina
