epoch data after pre-processing

The epoch data are a fieldtrip format structure, all epochs (ended with 'WrdOn') are aligned with fixation onset to a given word (as time 0), with a length of one second ([-0.5 0.5]s).Epochs were named as the combination of the acquisition date, subject code, and data type.Epochs that ended with 'BL_Cross' were the baseline period before the presentation of the sentences.This field 'trialinfo' is the information about each trial, the header of all columns is as follows:1- sentence_id: sentence number for this epoch2- word_loc: the location of the current word in a sentence3- loc2targ: location distance between the current word and target word; loc2targ for pre-target, target, and post-target are -1, 0, and 14- saccade2this_duration: saccade duration toward this word5- fixation_on_MEG: MEG trigger for fixation onset to this word6- fixation_duration7- NextOrder: next word location minus the current word location;Negative value indicates a saccade backwards to the previous words8- FirstPassFix: whether this fixation is the first for this word or not9- PreviousOrder: previous word location minus the current word location; negative value indicates saccade forward to the next word10- SentenceCondition: the current word is in a sentence with a low or high lexical-frequency target word; 1 -- low frequency, 2 -- high frequency11- PupilSize: averaged pupil size during this fixation
