Join species


ARB_NT/Species/Merge Species/Join marked species



WARNING: This module is obsolete by newer modules. See NOTES below!

"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.



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'.



There's a second, newer function to merge species: see ´Merge Similar Species´

There's a special new function to concatenate alignments: see ´Concatenation of sequences´



'Join marked species' does only merge fields of type STRING, all other fields are skipped (taken from one of the joined species).
