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.
