## Two folders:

- 'raw data' with edf files of each participant
- 'data prepared for analysis' with two behavioral files: behavioral_cue.xlsx and behavioral_gap_no_cue_xlsx (trials with/without cue presentation) and pupil measure: pupil.xlsx

## Relevant variables in `pupil.xlsx`:

- 'Recording session label' - subject number
- 'Trial_N': the ordinal number of a trial (without counting fixation break trials)
- 'Trial_Index': - the ordinal number of a trial from a pool of all trials (including fixation breaks)
- 'Bin index': the ordinary number of samples (20ms each)
- 'RT': reaction time on target (ms)
- 'Cond': condition (FIX=fixation trials, GAP=fixation offset trials, GAP_NO_CUE= trials where fixation point was removed and where cue was not presented)

- 'SOA': Stimulus onset Asynchrony (2000ms, 25000ms)
- 'Validity_n': type of trials (1 = cued; 2 = uncued and 0 = cue was no presented)
- 'Time' - time interval count from cue onset.
- 'Baseline_mean' - mean pupil size measured before cue onset
- 'Pupil' - pupil size measured after cue onset
- 'PUPIL_baseline': difference between baseline_mean and Pupil
- 'Condition1' - corresponds to the column termed: Condition1_name
- 'Condition2' - corresponds to the column termed: Condition2_name
- 'Condition3' - corresponds to the column termed: Condition3_name and Condition3_v2_name

## Relevant variables in `behavioral_cue.xlsx` and `behavioral_no_cue.xlsx`

- 'sub': number of participants
- 'TRIAL_N': ordinary number of a trial (without counting fixation break trials)
- 'con': condition (1=fixation trials; 2-fixation offset). Related to column 'condition_name'

- 'validity': 1=cued (valid), 2=uncued (invalid), 3= trials when the cue was not presented
- 'S': SOA (1=2000ms, 2=2500ms). Related to column 'soa_name'
- 'RT' - reaction time (ms)
- 'target': target presentation (left, right)
