Genetic breeding of perennial forestry crops often results in years of trial data, which can be time consuming to manage, search and reformat for analysis. Trial data for perennial species are stored over many years, and often with different platforms and naming structures. GEMview is designed to standardize and make all trial and pedigree information easily accessible on-line, which minimises errors and loss of information, as well as streamlines data management. In addition, users without any specialized programming knowledge can easily re-format, subset and extract data for analysis in the formats required in minutes.
