# Selections of Species (Configurations) OCCURRENCE DESCRIPTION NOTES ## OCCURRENCE
### ARB_NTREE/Species/Selections
## DESCRIPTION
### Each species is either marked or unmarked. All species that are marked are called marked species. In order to handle multiple sets of marked species we use configurations ( = selections of species). ### Several operations are possible with the configurations: STORE (save a (new) configuration) EXTRACT (= unmark all, then mark those from configuration) MARK/UNMARK/INVERT (mix currently marked species with those marked in configuration) COMBINE (unmarks all that are not in configuration. This does an intersection between the currently marked species and the selected configuration) DELETE (delete a configuration) RENAME (rename a configuration) ### Each configuration has a unique name and is part of the database. The current tree displayed within the ARB_NT main window is stored with the configuration. ### ARB_EDIT4 may load all marked species or all species stored in a configuration.
## NOTES
### Saving the database means also saving all configurations.
