The JUICE program was designed as a Microsoft® WINDOWS® application for editing, classification and analysis of large phytosociological tables. This software, with available maximum capacity of 65,000 relevés (predefined capacity is 30,000 relevés) in one table, utilises many functions for easy manipulation of table and header data. The program is optimised for use in association with TURBOVEG which is the most widespread database program for storing phytosociological data in Europe, even though the data import is also possible from a spreadsheet data format. Various options include classification using COCKTAIL, TWINSPAN and PC-ORD methods, calculation of interspecific associations, fidelity measures, relevé matching, average Ellenberg indicator values, preparation of synoptic tables or automatic and manual sorting of relevé tables. Easy simulation of artificial data for testing is possible. Export of final tables and different types of analysis (fidelities, species groups, indicator values, synoptic tables, diagnostic species etc.) is created in four data formats: (1) MS-DOS text, (2) Rich text format for word processors (e.g. Microsoft® WORD®), (3) spreadsheet format (e.g. Microsoft® EXCEL®) and (4) the database format (Microsoft® ACCESS®).  The program directly supports cooperation with the DMAP mapping package and creates the Cornell condensed files for other classification utilities such as CANOCO or PC-ORD). The JUICE program is continuously developed from 1998 as a freeware application in the group of vegetation science at the Department of Botany, Masaryk University, Brno, Czech Republic.
