Processing and preparation of eye traces for microsaccade analysis

The resulting output from the last script prep_for_BMD_and_preprocess.m is a .txt file - here S1_ORI10_BMD.txt- that is ready to be run with the Bayesian microsaccade detection algorithm, directly as input to ./bmd

Data

Sample data of one condition from one participant from Mihali et al, 2018, who performed the task version with eye-tracking.

Scripts

  • eye_script_1.sh acts on the raw Eyelink output and selects the trials that were completed without breaking fixation - the main output is S1ORI10_parsed.txt.
  • eye_script_2.sh acts on S1ORI10_parsed.txt and parses the trials into the trial periods and also provides time stamps for the beginning and ends of each. It provides several files as outputs.
  • prep_for_BMD_and_preprocess.mselects the trial periods of interest and glues the time series together accordingly to prepare for microsaccade analysis with BMD, hereS1_ORI10_BMD.txt.
