Menu: Export | JUICE input files

JUICE (Tichý 2001) is an excellent program designed for editing and classifying large phytosociological tables. The maximum capacity is 30.000 relevés in one table, and many functions are included for easy manipulation of phytosociological tables, including header data. Various options include calculation of average Ellenberg values for relevés, export of table data into other programs, mapping of species occurrence from actual data sets, etc.

JUICE includes TWINSPAN for classification, which is implemented as an external service. It is recommended for smaller datasets.

The most important feature of JUICE however, is the classification of relevés using the Cocktail classification method (Bruelheide 1995, 2000). This method tests the statistical coincidence of species occurrence in order to find reasonable groups of diagnostic species, as they are traditionally used in phytosociology. Vegetation classification is subsequently created by combination of different species groups.

Export to JUICE input files is a combination of a Cornell condensed species file and a user defined header data file. The latter is optional.

Target directory: Specify the directory to store the export file. Click to select a directory from a list.

Name for all export files (.cc!, .exp, .str): Enter the name for all the possible export files. The extensions are added automatically. In order to apply header data in JUICE, the prefix for all file names must be the same.

Combine/Exclude layers: Specify whether you want to combine species that are divided over more than one vegetation layer and/or that you want to exclude species that are present in one or more layers.

Include header data: Mark this options if you want header data to be included in the JUICE table.

Select header data: Select at least one header item to be exported.
Using Load and Save you can retrieve previously and save currently selected header items.

Please note that relevés first need to be selected before they can be exported.
