## 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
