It has user-provided data as input, that is filtered in order to evaluate temporal trends in the taxonomic community metrics for each site. This workflow is part of Marco-Bolo project task 5.1. 1 time series analysis European marine ecosystems Marco-Bolo taxonomic community metrics Andrés Peredo Arce Senckenberg Society For Nature Research andres.peredo@senckenberg.de MIT License Biodiversity data from excel retriever This is a NaaVRE workflow component / building block written in R that retrieves, validates, and saves biodiversity data and metadata from an Excel file for further processing. If the input file is not found in either location, the script stops with an error. It reads two sheets from the Excel file: Metadata and Data. It defines required columns for both data and metadata and checks if all required columns are present in the dataframes. If columns are missing or extra columns are present, the script stops with an error message. Finally, it writes the metadata and data to separate CSV files (metadata.csv and data.csv) in the temporary directory. https://metadatacatalogue.lifewatch.dev/srv/eng/catalog.search#/metadata/d9fc8450-10d0-4774-92af-257a1fc4e488 https://helpdesk.lifewatch.eu/ https://beta.naavre.net/jupyter/hub/user-redirect/lab/tree/Virtual%20Labs/Biodiversity%20Time%20Series%20Analyses/Git%20public/workflows/Biodiversity_time_series_analyser.naavrewf?profile=biotisan-euromarec WWW:LINK-1.0-http--link Link to the workflow in NaaVRE https://marcobolo-project.eu/wp-content/uploads/2025/12/MBO_D5.1_Nov-2025.pdf WWW:LINK-1.0-http--link Deliverable 5.1 Scientific document determining biodiversity trends, underlying drivers and essential observations for predictive modelling V1.0
