     - `Masterfile (.xlsx)`: This file stores the derived phenotypic measurements of the plants and a guide document.
-    - `HSI Data Processing Quality Control Data (.csv, .gif, under quality_control directory)`: This directory contains information for quality assessment of the HSI data processing pipeline. It includes summaries of header information for plants, white and dark reference (header_summary_plants.csv, header_summary_ref.csv), a detailed record of the processing procedures employed (processing_strategy.csv), and animated gif files used to check coregistration quality between visible and near infrared (VNIR) and shortwave infrared (SWIR) data. The filename conventions for gif files are same as [raw scanned data](https://github.itap.purdue.edu/PlantScience/DataExploration-AAPF/blob/main/DataGuide_AAPF_HSI.md#raw-scanned-data).
