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