 This GitHub repository provides a comprehensive resource for analyzing high-throughput phenotyping (HTP) data from the [Ag Alumni Seed Phenotyping Facility (AAPF, Purdue)](https://ag.purdue.edu/aapf/), including a detailed guide and a collection of data processing tools. It includes foundational [R](https://www.r-project.org/) tools for transforming AAPF data products (RGB, hyperspectral, X-ray) into an analysis-ready dataset ([long format table](http://www.cookbook-r.com/Manipulating_data/Converting_data_between_wide_and_long_format/)). This standardized dataset can be directly used in statistical modeling and visualization using R.
