Glossary

Subdatabase containing homologous sequences (different 'alignments' can be stored along with the species information). See ´What is an Alignment?´ for more information.

ARB Command Interpreter. ACI is a simple programing language for calculating special species information (eg. G+C Content..) See ´ARB Command Interpreter (ACI)´.

Branch within a tree defined by nodes

Container for 'species' associated information

Marking of 'species' defines the datasubset which is analyzed by the ARB tools. See ´What are Marked Species?´.

There are two kinds of name fields (for species, genes, etc.).

• name
  Identifier for 'species' entries. Should be generated automatically using the NAMESERVER (see ´ARB NAMESERVER / Synchronize IDs´).
• full_name
  User defined full name of the species,...

Node Display Setup: defines information which is displayed at tree nodes.

Internal: connects branches of a tree Terminal: free end of branches representing 'species'

Server using a special form of the ARB database for rapid similarity searching (automated alignment, probe design/check)

Sequence Associated Information (see ´SAI Administration´)

See ´Selected species´.

Database entry containing a sequence and associated information. Not necessarily consistent with a taxonomic species

Search and Replace Tool allows to search substrings in a string and replace them by another substring (see ´Search and Replace Tool (SRT)´).

Zombies are references to former species in a tree, i.e. to species that were in the database when the tree has been calculated, but have meanwhile been deleted (see ´Remove Zombies´)
