PuPl

PuPl processes pupillometry data as an Octave-compatible library of Matlab functions for preprocessing, trial management, and event-related pupil dilation analysis.

Key Features:

• Octave-compatible Matlab library: Collection of Matlab functions compatible with Octave enabling programmatic pupillometry data processing.
• Preprocessing (blink correction, smoothing, gaze correction): Provides blink correction, data smoothing, and gaze correction to remove artifacts and noise from pupil time series.
• Trial Management: Supports definition and sorting of trials for experiments with multiple conditions or stimuli.
• Event-Related Pupil Dilation Segmentation: Segments time series to isolate event-related pupil dilation responses.
• Flexible Data Export: Exports tabular data suitable for diverse statistical analyses.
• Extensibility: Designed to allow extension and user contributions to incorporate evolving pupillometry best practices.

Scientific Applications:

• Cognitive and neural mechanism studies: Enables analysis of pupil size changes to investigate cognitive processes and physiological states in neuroscience research.

Methodology:

Replication of published results using publicly available data to demonstrate the pipeline's capabilities.
