- Results are prepared for easy readout to transfer them to science4you entry masks.
- Results are shown with meta data, remarks, totals and species results per section.
- Results may also be exported in SQLite- or CSV-format and transferred to a PC for your own processing, e.g. by importing a csv-file into a spreadsheet like MS Excel.
