EyeLink EDF-to-ASC Converter

A generic R utility for batch-converting EyeLink EDF recordings into ASC files while preserving subject/session folder structure.

EyeLink EDF-to-ASC Converter visual

This is a small research-tooling project around EyeLink preprocessing. EyeLink recordings are often stored as binary EDF files, while many analysis workflows in R prefer ASCII ASC exports.

The utility wraps SR Research's edf2asc executable and batch-converts EDF files across a subject/session folder tree. It preserves the original folder structure in the output directory, making downstream parsing cleaner.

The project is presented as a reusable converter for EyeLink workflows rather than as a dataset release, with the focus placed on batch conversion and preprocessing automation.

Highlights

  • Generic R function with configurable input directory, output directory, edf2asc path, session recursion, and overwrite behavior.
  • Preserves subject/session folder organization during conversion.
  • Designed for downstream ASC parsing workflows, including eyelinker-style preprocessing.
  • Designed the utility as a lightweight preprocessing component for downstream eye-tracking analysis workflows.
