+
+This document details the file system organization and navigation procedures for accessing both unprocessed hyperspectral imaging (HSI) data and the derived phenotypic measurements of the plants captured by the [Ag Alumni Seed Phenotyping Facility (AAPF)](https://ag.purdue.edu/aapf/).
+
+- Raw Scanned Data: This folder structure houses individual scans (.hdr, .md5, .raw, .tiff) for each measurement.
+- Interim Data Product: This data contains data used for quality control procedures and images representing various vegetation indices.
+- Masterfile (.xlsx): This file contains a compilation of spreadsheets and a guide document explaining the data contents.
+
+
+### File system structure
+
+
+#### Raw Scanned Data
+
+Directories are named using a convention that incorporates both experiment number and treatment. Example: 407_WL, 407_WW, 401_20-1, 401_20-2, 401_80
+
+#### Interim Data Product
+
+
+The interim data product consists of three primary components:
+- Masterfile (`Hyperspectral_data_AAPF_experiment_{Experiment_No}.xlsx`): This file stores the derived phenotypic measurements of the plants and a guide document.
+- HSI Data Processing Quality Control Data (`quality_control`): 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, a detailed record of the processing procedures employed, and animated gif files used to check coregistration quality between visible and near infrared (VNIR) and shortwave infrared (SWIR) data.
+
+
+- Compressed Vegetation Index Images (`{Vegetation_Index_Type}_{ROI filter}.zip: This section houses compressed image files for various types of vegetation indices calculated from the HSI data (ROI: region of interest).
+
+
+
+Animated gif files are included to check the coregistration quality between VNIR and SWIR data per each scan.
+
+Co-registration quality between VNIR and SWIR data for each scan is visually assessed using animated GIFs
