Paprika — VIS–NIR & SWIR tables with biochemical fields

# Paprika (Capsicum annuum) — VIS–NIR & SWIR tables with biochemical fields **Version:** 1.0 (date: 2025-11-04) **Maintainer:** Jesús Alonso Sánchez (ICTAN-CSIC & INURA-UEx) ## OverviewThis dataset provides the cleaned input tables used for the comparative preprocessing and PCA analyses in the paprika study. The files include VIS–NIR (FX10) and NIR–SWIR (FX17) reflectance spectra (`R_...` columns) together with selected metadata/biochemical variables. The column `EMPRESA` was removed for anonymization. ## Files- `FX10_con_bioquimicos_PUBLIC.xlsx` — VIS–NIR table (Specim FX10).- `FX17_con_bioquimicos_PUBLIC.xlsx` — NIR–SWIR table (Specim FX17).- `CHECKSUMS.sha256` — SHA-256 checksums for integrity verification.- `CITATION.cff` — citation metadata (YAML).- `METADATA_zenodo_template.json` — template with deposition fields. Schema (common elements)- Spectral columns prefixed with `R_`.- Grouping column auto-detected in scripts: `Año`, `Anio`, `Year`, or `Tratamiento`.- Additional biochemical variables as present in each file. ## UsageThese files are the expected inputs for the MATLAB scripts in `code-matlab/03_preprocessing/`:- `preprocessing_pca_fx10.m`- `preprocessing_pca_fx17.m`
