# Join species OCCURRENCE DESCRIPTION EXAMPLES NOTES WARNINGS BUGS ## OCCURRENCE
### ARB_NT/Species/Merge Species/Join marked species
## DESCRIPTION
### "Join species" merges several similar species into one species. ### All database fields and the sequences get concatenated. Mark all species that should be examined for similarity. Select a database field entry from the list to set a similarity-criterion used to detect candidates for joining (for e.g., full_name). Check separators for fields and sequences. Press GO to start.
## EXAMPLES
### For example you have a 23s and a 16s database and you want to append the 16s to the 23s sequences than you have to do: merge the 16s to the 23s sequences. create a field 'species_name' which holds the real name of the species. That means the species_name of the 16s sequence should be the same as of the 23s seq. Do not use the 'name'-field because it is used as a UNIQUE id to the database. ARB_NT/Species/Merge Species/Join Marked Species and use the field 'species_name'.
## NOTES
### There's a second function to merge species: see ´Merge Similar Species´ ### There's a special new function to concatenate alignments: see ´CONCATENATION of ALIGNMENTS / SEQUENCES´
## WARNINGS
### 'Join marked species' does only merge fields of type STRING, all other fields are skipped (taken from one of the joined species).
## BUGS
### No bugs known
