The VESPUCCI compendium is a complete and comprehensive database of nearly all transcriptomic experiments performed on grapevines using both microarray and RNA-seq data. It is organized as a single coherent expression matrix in which each row represents a gene and each column represents a condition. Data are normalized using different strategies, either log ratios for both microarray and RNA-seq, to compare coexpression patterns across all conditions, or TPM for RNA-seq experiments only. The database can be queried programmatically using the GraphQL interface (COMPASS, http://vespucci.fmach.it/compass), the Python or R packages (https://pypi.org/project/pyCOMPASS/ and https://github.com/onertipaday/rcompass).
