Introduction

This is a guide on how to perform the data preparation steps. There are four chapters covering each of the steps and an additional chapter for eye tracking data.

Navigate the Chapters from the left-sidebar.

Before we can start even looking at the data there are some preparatory steps that need to happen. Data Preparation starts out with messy raw data files for each individual subject spread across all the computers and ends with tidy raw data files (that are easy to work with) with data from all subjects merged into one file for each task.

The four data preparation steps are:

  1. Organize the raw data files

  2. Merge the individual .edat files into a single task.emrg file using E-Merge

  3. Export the task.emrg file to a task.txt file so we can process the data in R

  4. Tidy the raw data files by running the 0_task_raw.R Scripts

All the data files related to the study will be in the Z Drive at:
