This function builds upon the eyelinker::read.asc() function to parse the
messages and metadata within the EyeLink .asc file. After loading and
additional processing, this function returns an S3 eyeris class for use in
all subsequent eyeris pipeline steps and functions.
Arguments
- file
An SR Research EyeLink
.ascfile generated by the official EyeLinkedf2asccommand- block
Optional block number specification. The following are valid options:
"auto" (default): Automatically handles multiple recording segments embedded within the same
.ascfile. We recommend using this default as this is likely the safer choice then assuming a single-block recording (unless you know what you're doing).NULL: Omits block column. Suitable for single-block recordings.Numeric value: Manually sets block number based on the value provided here.
Value
An object of S3 class eyeris with the following attributes:
file: Path to the original.ascfile.timeseries: Dataframe of all raw timeseries data from the tracker.events: Dataframe of all event messages and their timestamps.blinks: Dataframe of all blink events.info: Dataframe of various metadata parsed from the file header.latest:eyerisvariable for tracking pipeline run history.
Details
This function is automatically called by glassbox() by default. If needed,
customize the parameters for load_asc by providing a parameter list.
Users should prefer using glassbox() rather than invoking this function
directly unless they have a specific reason to customize the pipeline
manually.
Note
This function is part of the glassbox() preprocessing pipeline and is not
intended for direct use in most cases. Provide parameters via
load_asc = list(...).
Advanced users may call it directly if needed.
See also
eyelinker::read.asc() which this function wraps.
glassbox() for the recommended way to run this step as
part of the full eyeris glassbox preprocessing pipeline.
