The PubChemLite interface is based almost entirely on the information available in the archived PubChemLite-CCSbase CSV files (see Figure ), except that additional synonyms (excluded from PubChemLite files for efficiency) are retrieved from the PubChem FTP site for better searchability. Additionally, records are enhanced with visualizations of the annotation categories and tables of the CCS and associated adduct mass values. Finally, the chemical stripes are included where available for both literature and patents (see Figure ). The original chemical stripes R version was rewritten in Python for integration in PubChemLite-web, with code available in both repositories .
