## OCCURRENCE

### ARB_NT/Tree/NDS

### ARB_GENE_MAP/Properties/NDS

## NOTES

### Read this text carefully. You won't need this function, but it offers many many new possibilities.

## DESCRIPTION

### Extracts data from the database entries of every species and builds a user-readable string from that data.

### This string can be used in many different functions, especially to show the species information at the tips of the tree or to show gene information at the tips of the genes in the gene map.

### It allows you to show part of the sequences, the full_name, the accession numbers right in the tree. You may even generate tables with all kinds of useful information, like probe match results for a set of oligo probes.

### Choose the 'NDS' item from the 'ARB_NT/Tree' menu to display the 'NDS' window.

### Enable field extraction:

Press the 'LEAF' and/or 'GRP.' checkbox to activate the display of the corresponding 'field' entry at leafs and/or groups of the tree shown in the tree display area of the 'ARB_NT' window.

### Select 'FIELD':

The order of the data shown at the tree nodes (from left to right) corresponds to that in the 'NDS' window (top to bottom). To select a 'field' enter the field name by hand or press the respective <S> button and select it from the popup-list.
Press <RESCAN> there to display all fields, if fields have been deleted from the list by 'Species Information/Delete hide fields'.

### Define number of characters:

Type the number of characters (including blanks) to be displayed to the 'WIDTH' subwindow.

### Display SRT/ACI:

The 'Search and replace Tool (SRT)' and the 'ARB Command Interpreter (ACI)' in combination with 'Nodes Display Setup (NDS)' allows information to be extracted and/or modified from the 'Field' entries, before being displayed at the tree nodes.
Press the corresponding <SRT> button to display the 'SRT_ACI_SELECT' window and select a predefined procedure (see ´Predefined SRT/ACI´).
The corresponding syntax (see ´Search and Replace Tool (SRT)´, ´ARB Command Interpreter (ACI)´ and ´Regular Expressions (REG)´) is displayed in the 'ACI SRT PROGRAM' subwindow. The displayed strings can be modified by typing to the subwindows.

## NOTES

### Strings generated using 'SRT' or 'ACI' and displayed at the nodes are not stored in the database. You can use the 'Modify fields of listed species'-menuentry in the 'Search & Query' window to do this.

### The width of the output is limited to 4000 characters.
