Explanatory_Videos.zip has videos showing data collection methods. 
HIDA_Publication.R has source code for doing data cleanup and analysis on data in database.zip. 
databasedata.zip holds all raw and analyzed data. 
- ATR, Reflectance, and Transmission folders has all data used in the manuscript. In a raw (.0) and combined (export.csv) format for each of the plates analyzed (folder numbers). 
- Plots folder has images of each spectrum. 
- cell_information.csv has the raw ids and comments made at the time the particles were assessed. 
- classes_reference_2.csv has the transformations used to standardize open specy's terms to polymer classes. 
- CleanedSpectra_raw.csv has the total cleaned up database of all spectral intensities in long format.  
- joined_cell_metadata.csv has the metadata for each plate well analyzed. 
- library_metadata.csv has metadata for each spectrum in raw form for each particle id. 
- Lisa_Plate_6.csv has the metadata from Lisa Roscher used in this study. 
- Metadata_raw.csv has the conformed metadata that can be paired with the CleanedSpectra_raw.csv file. 
- OpenSpecy_Classification_Baseline.csv has the particle metadata combined with Open Specy's classes identified after baseline correcting and smoothing the spectra with the standard Open Specy routine.
- OpenSpecy_Classification_Raw.csv has the particle metadata combined with Open Specy's identified classes if using the raw spectra. 
- particle_spectrum_match.csv converts particle ids to their reference in the Polymer_Material_Database_AWI_V2_Win.xlsx file. 
- Polymer_Material_Database_AWI_V2_Win.xlsx metadata on materials from Primpke's database. 
- polymer_metadata_2.csv can be used to crosswalk polymer categories to more or less specific terminology. 
- spread_os.csv is the reference database used in CleanedSpectra_raw.csv that has been spread to wide format.
- Top Correlation Data20221201-125621.csv is a download of results from Open Specy's beta tool that provides the top ids from the reference database.
