Create a Darwin search

To access Darwin Search interface in Pirana:

Custom options

Validation of entries in the Darwin Search properties window occurs on all of the pages. If there are any invalid fields, that field, as well as the page name in the tree on the left, will be highlighted in light red.

When the Save button is pressed, a .drwn zip file is created containing:

advan_tree: ADVAM/covariate related information

data: all auxiliary information about the Darwin Search properties window settings
