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 filed 'trialinfo' is the information about each trial, the header of all columns is as followings: 1- sentence_id: sentence number for this epoch 2- word_loc: the location of the current word in a sentence 3- loc2targ:location distance between the current word and target word; loc2targ for pre-target, target, post-target are -1, 0, and 1 4- saccade2this_duration: saccade duration toward this word 5- fixation_on_MEG: MEG trigger for fixation onset to this word 6- fixation_duration 7- NextOrder: next word location minus the current word location; negative value indicates saccade backward to the previous words 8- FirstPassFix: whether this fixation is the first for this word or not 9- PreviousOrder: previous word location minus the current word location; negative value indicates saccade forward to the next words 10- SentenceCondition: the current word is in a sentence with incongruent or congruent target word; 11 -- incongruent, 2 -- congruent 11- PupilSize: averaged pupil size during this fixation
