SampleManager 2002 incorporates advances that are designed to enable scientists to make more informed decisions based on improved capabilities for analyzing, searching, reviewing, and reporting laboratory data. A highlight of the new functionality is the Calculation Builder that provides users with a facility to simplify the creation of complex calculation formulae. It features tools to create calculations across different sample types and allows users to use previously saved data-searching criteria in their calculations. An extensive library of mathematical functions is also included. The LIMS’ newly enhanced Selection Criteria function offers users a highly graphical and intuitive interface from which to explore, query, and view subsets of sample data filtered from multiple tables within the LIMS database.
