## OCCURRENCE

### ARB_NT/Species/Mark by reference

## DESCRIPTION

### Allows to mark all species referred to in the content of a field.

### Select whether to check all or marked species.

### Enter name of field containing references.

A reference is a single species ID ('name') or a comma-, semicolon- or space-separated list of species IDs.

### Choose whether

- to abort if the field is missing or
- to continue w/o warning

### Enter an ACI expression (see ´ARB Command Interpreter (ACI)´) to postprocess the field content. The result must be a reference or reference-list (see above).

### The default ACI is '/[0-9.]+[%]*://'. This works with several common references (like 'used_rels' from fast-aligner or relatives written by 'Search next relatives')

Below the ACI there are 3 lines showing

- the selected species
- the content of its field
- the result after processing it through the ACI

### Choose whether

- to abort if an unknown reference is found or
- to continue w/o warning

### Click 'Mark referenced' to mark all species which are referenced by the examined set of species.
