Automatic Eye Scoring

R code to identify and score saccades along the horizontal meridian.

Available in /Volumes/Hera/Projects/autoeyescore and on https://github.com/LabNeuroCogDevel/autoeyescore/

See github readme citation section for how this code is cited in manuscripts from the lab.

trialwise scoring includes

  • trial number
  • xdat 0-265 code describing trial target (fix, pro, or anti saccade, side: far,near left,right)
  • latency trial onset to onset time of first saccade (ms)
  • trial score
  • drop reason description when dropped
scoremeaning
-1 Dropped – blink, too fast, bad tracking, etc
0 Incorrect – looked at the wrong side and never corrected
1 Correct – first saccade to the correct side
2 Error Corrected – first saccade to the wrong side, but next saccade to the correct side

Trialwise scored files look like: 

head /Volumes/L/bea_res/Data/Tasks/Anti/Basic/11723/20181119/Scored/txt/11723.20181119.1.trial.txt 

trial   xdat    lat     fstCorrect      ErrCorr AS      Count   Desc

3       134     405     TRUE    FALSE   AS      1
4       134     164     FALSE   TRUE    AS      2

7T

Brain Mechanisms R01 (7T) used the ASL 60Hz eye tracker. Collection of all trialwise scores in /Volumes/L/bea_res/Data/Tasks/Anti/all_trials_7t.tsv 1)

Final trail-wise scored files are like /Volumes/L/bea_res/Data/Tasks/Anti/Basic/1*/2*/Scored/txt/*.1.trial.txt

  1. Raw scan data is copied from the eye tracking computer to L:\Data\Temporary Raw Data\7T
  2. /Volumes/L/bea_res/Data/Temporary\ Raw\ Data/copy7T.bash makes copies into bea_res/Data/Tasks/Anti/Basic/1*/2*/Raw/EyeData/*.eyd
  3. in /Volumes/Hera/Projects/autoeyescore, ./runme.bash -t anti conversts .eyd to .data.tsv and creates Scored/txt/*.1.trial.txt files.
