ARB_NT Main Window

DESCRIPTION

'ARB_NT' is the main window for the current ARB database and provides access to all ARB tools for analyzing and modifying this database via menus or buttons.

The tree shown within the tree display area can be used to walk through the database, to structure it according to phylogeny, and to display any information stored within the database at its nodes.

 

ARB menu

Clicking on the prompts in the horizontal menu bar in the upper part of the window displays the corresponding submenus. The submenus are also available using keyboard shortcuts by pressing the meta and a letter key indicated in the main menu bar by underlining.

File:
Save the database, export or import data. Open second window or database. Macro recording and playback.
Species:
Create, rename, delete, convert, mark, unmark, colorize, search or display 'species' and their associated fields. Synchronize species IDs.
Sequence:
Create, copy, delete, rename, check, concatenate or modify 'alignments' (see ´Glossary´). Edit, align, translate or realign sequences. Calculate similarity and distance matrices, profiles or filters.
SAI:
Copy, delete, rename, convert or combine SAI (sequence associated information). Calculate consensus and positional variability.
Probes:
Probe and Primer design and matching. Handle 'PT_SERVER' (see ´Glossary´);
Tree:
Copy, delete, import, export, print, compare, or modify trees. Reconstruct phylogenetic trees. Calculate consensus trees. Curate taxonomy, fold clades. Configure node display (NDS).
Tools
A collection of different functions which did not fit well elsewhere. All external programs configured via GDE are listed here as well.
Properties:
Customize display of windows, trees and data. To save these settings for future sessions choose 'Save properties'.
Many menu entries are linked to explicit help pages. To visit such a help page, click the green '?' and then the menu entry you'd like to read about. See also ´Using embedded help´.
